LAN isnt fast enough...

TEH WIN · Post by **TEH WIN** » Sun Dec 16, 2001 3:15 am

I have my 100mbps full duplex lan up in my house. there are a total of 3 comptuers on 2 switches (actually, 1 switch and 1 router)

i transfered a very large file between two comptuers which are relativly fast... both 450 mhz. but the max it ever transfered was 41mbps and averaged at around 38mbps mind you, this is a 100mbps LAN. i know ill never get 100mbps.. but i expect better than 41. network cards are 3com and linksys, all name brand stuff

how can i increase this?

Try using NetCPS to measure throughput. Name brand, yeah, but good quality, well, 3COM, yes, Linksys...well, heh, and I'm guessing you're using the little built in switch in the router, which is really just a little 30 dollar switch, not a switch like 3COM SuperStacker III switches.

Which OS are you using?
Which protocols are you using?
What are your NIC's set to?
Are your NIC's sharing any IRQ's with anything else?

WinXP on the source machine, Win2k on the Destination machine
Default protocols that it installed on its own, i never messed with them
NIC's are both at full duplex
The win2k machine is sharing an IRQ with the USB controller. I'm not sure about the winxp machine.

Its actually running thought 2 switches... it went from the 2k machine thru a 3 foot cat5 to the router/switch down a 50 foot cable (through the attic if that matters) to a 5 port linksys switch, to a 7 foot cable to my win2k machine

you can always do what i am about to do, add anic in each pc and bridge connections for lan. Also i would try netbeui, and 50 feet of cat5 will decrease performance. Plus if you can eliminate one fo those hops. I mean take out the switch and maybe go straight intot the router? If you can't you can't but that would help also.

Please explain how 50 foot of cable decreases performance. (haha - this will be funny, hey norm

Get a hold of NetCPS and post some results.

well lets see, either alllllllllllllllllllll of the books i read, network +, mcse, cisco, ect ect are wrong and they are right, or the books are right and these idiots are wrong, hmmmmmmmmmm.........................(syclone weighs the possibilities......................) i go with the books. I go with the ppl that know wayyyyyyyy more than me or anyone else on here. They are the type of ppl that work with this stuff day in and day out. If you want me to quote the books just say the word and you will look that much more foolish. hey i guess yall think it doesn't matter for dsl speeds how far you are from the co too huh?

Syclone,

I work with these things day in, day out (yes, gets a little boring at times).

I wouldn't go so far as to say that the the authors of an A+ or a CCNA book know more than everyone on these forums, because that is most likely incorrect. There are some very experienced people here, like Kipp Patterson, YeOldeStoneCat, etc who know what they are talking about - probably more so than a person who writes a book for an entry level 'certification'

I will set this thread to rest once and for all.

If you research the IEEE standards you will find that the ethernet specification yields a maximum length of 100 metres (approx 328 feet) before the standard is no longer matched, in a single cable run. If the performance of the communications link were to degrade after 50 feet, the standard would be false.

Now, we can clearly see that the standard is what is going to prevail, otherwise it wouldn't have been made in the first place! (Further, I've dealt with alot of ethernet which runs over 50 feet, which are perfect - they do not degrade as you suggest).

Regarding xDSL performance - yes - we know distance is a variable. I have done extensive testing and performance measurement on all sorts of loops - let me know if you want further info

(unfortunately, they don't publish this info in A+ books

)

I find it very hard to believe that a series of books would claim that ethernet performance does indeed degrade over 50 feet. I find it much more probable than a recently certified A+ student with no experience suggests that.

Did you know that mcse, ccna, ccnp, ccie, ect ect quote the ccitt, itut, ieee, ect ect? and i am sorry but, i would bet that a ccie knows wayyyyyyyyyyyyyyyyy more than everyone on this forum combined. I have seen more false statements, and ppl talking about things they know nothing about on here. ok, if a signal doesn't degrade, why get a switch to boost its strength? And i have been on lans for gaming dozens of times and the shorter the cable run the better. how about you make a longgggggg cable and transfer a huge file on lan, post the speed, i will runa cable wayyyyyyy shorter and test my speed, lets see who gets the better performance? how about that? will that shut you up? Hey phantom, do u believe this guy? Oh and you will find that i say it as i see it, and i don't really care what some guy who sits ina cubical all day that designs stuff says, if i purchase it and it performs better or worse than its rated or what have you thats what i go by, regardless, i mean books are good, understanding theories is a plus, but if you see first hand that it isn't always the case then thats how it is, sorry. oh and btw i got a+ years ago, quit making false assumptions, thats the mark of someone with lower intelligence.

If your ethernet performance degrades over a length of 50 feet - you have severe issues - which aren't related to the ethernet spec. As mentioned, I have runs of cat5 which are far far longer than 50 feet, with absolutely no issues.

By the way, the key aim of a switch is not to boost a signal. it is for port aggregation. If you wanted a signal booster - there are commercial ethernet extender units available.

People with certifications annoy me - they are often 'book' people - with no real world experience to actually know anything.

Not suggesting you are one bit , so don't think I'm having a dig at you.

just to change the subject since this is going nowhere, if you get a job where you grew up, you need 0 paper (degrees, cert, ect) but if you move and ppl there don't know you from joe blow then you need something to ease there concern as to your level of compitence. Thats why you get certified, not because it makes you any more intelligent. Some ppl will argue that it does since you had to study for it of course, but if you know your ****, you know your ****, regardless of what any piece of paper says. I hate the school system and i have 4 parents for teachers, go figure!

Syclone D-...If you're thinking you're transferring faster on a WAYYYYYY shorter cable at some LAN party, well, first of all, must be a boring LAN party, because all the LAN parties I've helped setup, we play games, not sit there measuring throughput through our Cisco Catalyst switches. Also, I doubt what you consider a true comparison was a true comparison, as I'll bet it was an amateur garage LAN party with a mixture of hubs and switches and NICs, so who knows what you were transferring from from CompA to CompB, and from CompA to CompC, and were you using the exact same NIC's on all the computer to truely compare? Nah. I'm sure they were all a mix of computers and various hardware....not exactly the scenario for a true comparison. Gotta have the same OS, the same updates installed, the same protocols being run, the same exact hardware setup for system resources. Also, your so called WAYYYYY longer patch cable, was it, first of all, a quality one? Or one "home-grown" by someone using some no-name cheap spool and thinking he knew how to terminate them properly. And was that long run properly laid out, not coiled up in some pile being stepped on, and laying across a huge pile of daisy-chained surge strips and extension cords giving off tons of EMI. That can lead to lots of "attenuation"....oooohh...surprised we haven't seen your A+ book terminology throw that one out yet...or did that big word come in Network+, ah well, too long ago.

Because if you follow the specs, the max distance for CAT5 can be obtained without degradation of performance. That's what specs and rules are for.

After the first week of seeing your name throw spam up on these boards, I can't believe they're still letting you post here.

grammar, spelling, you said filed not field! maybe you should work on spelling too? and yosc, i am not the one that posts benchmarks on hardware not properly compared, due to different brand names, ect ect, you do. And why if i mention one thing do all of you focus on it, ex i list 10 books, but you single out a+, how about you list all of your math books you ever studied for school and i pick out basic algebra. Even though you would have listed titles like calculus, differential equations, ect, how about i just pick beginner's algebra and judge you by that? How do you feel? My point there was just to refute your statement about me always quoting a+, if i remember right i think i only had like 2 questions on the a+ test on networking, thats not whats it geared towards, hence why i study cisco, mcse and network+. And please chill with the putting words in my mouth and saying how i test things, how do you know what i do? I mean, i have had some ppl on here give me good arguments and i like and respect that, but don't focus on one cert that doesn't even deal with networking and down it. I wish i could change my name on the fly, or i might just make a new name and not tell anyone. I bet the attitude on here would be totally different just because i don't have that A+!

Ha ha , Syclone just trying to get a rise outta you guys and he is succeding!!!!!He said he could but I didnt beleive him........he is proving me wrong, cmon grow up who cares about 50 ft or a million ft of cat5, nobody cares.

Some of you people take this site waaay to serious for me, all this I know more than you crap point is nobody cares.I dont care what anybody knows on here.I need no help, I only jump on here to get a laugh or just see whats up, maybe try to help 1 or 2 people but seems everybody wants to argue with one another its eithier attacking somebody about bad grammer or saying how long they have been doing this or that blah blah or how many post they have blah blah, please to god stop with the grammer corrections (all b.s aside thats really gay).We all make grammer errors once in a while but who cares???

I jump on 8 different forum sites time to time and this is the most tense ,****y ,quick to stomp people ,no it all ,unhealthy serious , forum I have ever seen.There are some cool people here but seem to get less and less??Really people,suppose to be helping people out , maybe joke a little ,nobody is better than anybody else here......so all get off the high horse.

Also please ,please stop being such a hypocrite ,I have seen many quote things out of books from regular members on here ,web sites, etc etc ,so what.....whoooopdeeedooo ,you guys are quick to say somebody is quoting something when they type something that might be good material, you guys make it sound like people are invading your "turf" so to speak so you bash people.

I notice how when somebody thinks different you "some of you" you get offensive?????Why........be open minded, to many set ways here.I bet I will never see the day somebody on here will not bash somebody else about grammer,legal issues,newbie crap and prying into business of others.I dont understand this site at all seems to political and stressful.Sick of the Ati ver Gf and the nintendo ver xbox and all the old news threads and yes before you start on bashing me, dont sweat it im moving to another forum so gl SG.C-ya

Okay, the second you start criticizing OTHERS for poor spelling and grammar, you've already thrown away the rest of the post. I haven't seen ONE POST from you that demonstrates proper use of spelling and grammar. In fact, I believe the entire belief of a sentence structure escapes you!

Take offense, please. You show a lack of knowledge, rationing, and even basic courtesy in your posts. Frankly, they are a waste of time and space, and I honestly worry if you actually believe in what you write, because frankly, it scares me to know that you'd think that. Quite while you're behind, and save us both the trouble.

Having done the CCNA enables you to login to a router, and change the IP address. They don't go much further than that ! (I know, we have CCNA's/P's/IE's at work).

You do not become overnight internetworking expert from it.

Just pause for a moment, and absorb the wealth of information you're being provided with. As I mentioned, it will save you great embarssasment one day.

Wow, that did go off on quite a tangent!
Regarding the router, you will add latency because the route has to strip off and rebuild each frame before forwarding it. Can you configure your cable run so all 3 cables go into the switch and just run the switch off the router for firewall protection?
I'll be sitting on broken glass waiting for the next post.

not possible

eddiec · Post by **eddiec** » Fri Dec 21, 2001 10:23 am

Well, perhaps you could add a hub off the router to collect the single PC and the segment off the switch (still trying to keep all your PC's from switching through the router). However the more hardware you add the greater the possibility off additional problems. Try to borrow one off a friend and see if it will help.

Or if you're a daring type, you could screw with the CAT 5 and split it into 2 X 2 pair lines; one pair to each of the switched machines and relocate the switch. CAT5 in ethernet only uses 4 of the 8 wires, 2 for data transfer and 2 for collision detection on half-duplex, or 2 for transmit and 2 for recieve on full-duplex. The pins that are active are 1,2,3 & 6 (WHT/GRN, GRN, WHT/ORG & ORG).
So if you make a second connection using the remaining wires you have effectively created a second dedicated line. Cut off only enough of the outer jacket to have each connector reach a port on the switch, move the switch to the router location and cascade the switch off the router and all computers into the switch. Now assuming the two computers currently on the switch are close enough together split the other end of the long cable between the NICs on each machine.
The wiring scheme can be any you like but make sure it is the same on both ends and be sure to use pins 1,2,3 & 6. And don't take out any more twist in the pairs than needed (max 1/2")
I've asked a moderator for verification on this proceedure, so don't start snipping until it's checked out.

Kip Patterson · Post by **Kip Patterson** » Fri Dec 21, 2001 10:56 am

You can split a cable. I've done it on 10baseT on a 400' underground phone cable with success, as well as on 25-pair phone cables left over from a Bel 1-A keyset installation.

I'd expect 100baseT to be a little trickier, but wopuld expect it to work.
