100/10 tweaking help!

KontoS · Post by **KontoS** » Fri Mar 17, 2006 10:18 am

Hello!

I have 100/10 Mbit from BBB but I only get ~65Mbit TCP and the same on UDP.
TCP Analyzer says this:

TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default TCP Receive Window (RWIN) = 64240
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 64240

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44) <-- current value

bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms
Your TCP Window limits you to: 1027.84 kbps (128.48 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 56 hops
TTL value is ok.

Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00110000 (48)

Precedence (priority) = 001 (priority)
Delay = 1 (low delay)
Throughput = 0 (normal throughput)
Reliability = 0 (normal reliability)
Cost = 0 (normal cost)
Check bit = 0 (correct, 8th checking bit must be zero)

DiffServ (RFC 2474) = AF12 001100 (12) - Assured Forwarding class 1, medium drop precedence (RFC 2597).

The values I have in TCP Optimizer is now:
TCP Recieve window: 128480
TTL: 64
MTU Disc. Yes
Black Hole: no
Selective ACKs: Yes
Max Duplicate ACKs: 2

Nothing in the TCP 1323 Window.
But this doesnt do much for me. It leaves me with the same speed I got before the tweak :/

Try thease in the sg optmizer below me to download and install

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU - 1500
TTL - 64
TCP Receive Window -128480
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - uncheck
Timestamps - checked
Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 5
Host Priority - 6
DNSPriority - 7
NetbtPriority - 8
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 240
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect

VERY IMPORTANT TO DO THE FOLLOWING:
1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need. For a stand alone pc all you need is Internet Protocol TCP/IP.
2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.
3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer and set your duplex mode to "auto". If you are using a router make sure you have the latest firmware.
4. Clean out your temporary internet files with CrapCleaner.
5. Power cycle your modem i.e. unplug it for at least 15 seconds.
6. Download, update and scan with SpyBot S&D 1.4 EXACTLY as mnosteele has explained HERE & Ad-Aware SE 1.06 EXACTLY as mnosteele has explained HERE to remove any spyware then install and update SpywareBlaster 3.4 to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES. If these 2 programs find a lot of things then please post a HijackThis 1.99.1 log for us to look at.
7. Make sure you do the faster web page tweak in our Help & Tips page.
8. If you have Zone Alarm as a firewall uninstall it and search your pc for the left over files.
9. Install Kerio Personal Firewall 2.1.5, it's FREE and uses next to no resources.
10. Do a FREE online virus scan from Kaspersky Webscan, make sure to check the option to use the EXTENDED DATABASE.
11. Make sure you have ALL of the latest Windows Updates.

8) ;D

Okey tested the settings but... My computer started lagging momentarely sometimes... It's very annoying. The music or whatever I'm doing stops responding

I installed a new driver for the NIC, can that be the problem? It's a 3Com Etherfast XL. Plz help

[Edit] Instead of rebooting ur computer, can't u just restart the NIC? [\Edit]

Have you tried to update the drivers to your sound card? And yes.. reboot the computer (not just the NIC).

Triplate · Post by **Triplate** » Sat Mar 18, 2006 7:01 am

Get your RAM up to 2 Gigs....

KontoS · Post by **KontoS** » Sat Mar 18, 2006 9:24 am

Upgrading the sounddrivers didn't do it

And why would 2 Gigs of ram help me? I currently have 1,5 Gig and I didnt have the problem before I tweaked :/

KontoS · Post by **KontoS** » Sat Mar 18, 2006 9:38 am

How do I uninstall every tweak? Is there some default values I can use cuz this isn't working! And I have 1.5 Gigs of ram and I didn't do this b4 the tweak so I don't think it's the ram. Did try new soundcard drivers but they did nothing. :/

Gah... Something went seriously wrong with this one. I have restored windows default settings and went back to my old NIC driver and STILL it lags when my NIC is working. Need more advice plz!

Did you reboot?

Yes I did

Post a tarcert to a couple of sites ram has nothing to do with connection speeds. Might want to try to replacing the network cable making sure it's in the card right if it's loose it will cause it to lag.

Are you running any software firewalls using a router?

Triplate · Post by **Triplate** » Wed Mar 22, 2006 8:05 pm

RAM has tons to do with it.......but if you dont know by now, ..i cant explain it..lol*

mccoffee · Post by **mccoffee** » Wed Mar 22, 2006 10:25 pm

NO it doesnt' your line speed is determed by the rate you pay for the latency on the network being the isp should have network that is fully converged when it's not converged then latency on routes will slow you down. Line quailty or in the case of cable signal. Distance from the central office in the case of dsl and T's connection are usually the main factors for latency and speeds aswell as network convergence.

Why ram has nothing to do with it line speed the only time ram would effect speed is if there is leak that doesn't mean it's the Isp's fault he is slow it just appers slow locally since the ram is leaking

If you send a packet on two machines on the same network connection type of media no matter how much ram the packet will travel at the same amount of time

Triplate · Post by **Triplate** » Wed Mar 22, 2006 10:30 pm

I,m fully versed in all that ,Chief...but i guarentee you..the machine with 2 gigs is gonna compute faster than one with 512..that includes processing packet data...cheers!

mccoffee · Post by **mccoffee** » Wed Mar 22, 2006 10:34 pm

When it hits the machine locally in theory yes that doesn't cover the network traffic lmao how is ram going to effect the other machines routers on the network it doesn't matter.

The ram only effects probably the caching of web pages, games running locally you can have three gigs of ram with a bad network it will lag . Try this play a game on a dial up connection and upagrade your ram then.

Triplate · Post by **Triplate** » Wed Mar 22, 2006 10:38 pm

I dont play games ,man...what you just said is correct..but thats not what I get from the OP ...no biggie..have a good one!!

mccoffee · Post by **mccoffee** » Wed Mar 22, 2006 10:40 pm

Who is the op you are getting this information from?

mccoffee · Post by **mccoffee** » Wed Mar 22, 2006 11:03 pm

yeah but 1.5 gigs is more to handle any application especilly sound. If it's a music stream it's probably the buffering of the packets. If it's just an mp3 it's probably a buggy driver ,or some other hardware conflict of resources, maybe to many software resources being used.,or one application that is using alot that could be taken off startup. It could be a million things really maybe there is something infected in the machine. The os needs to be reinstalled. Hard drive needs to be defragged

1.5 is plenty of ram

Triplate · Post by **Triplate** » Wed Mar 22, 2006 11:13 pm

Yes..but, in fact, i noticed a considerable jump going from 1 to 2 gigs on this 64bit box..i have 6 other puters with vatious OS,s and RAM counts...in my opinion..you cant feed XP enough RAM...VISTA is said to be worse..although i never ran the BETA ..we,ll see ,i guess.

Right I agree some os's require more ram then others if you have a gig or more your good to go and even then some people install three and never really fully utilize it that's all i'm saying in 64 bit you can use all the ram for one application which is nice that's why if you run cad, video editing, graphic design, you will need it.. Now adding ram will speed it up ,however it's not only ram that bottle necks the registry builds up clutter over time, quick launch/system tray in 2k has more applications loading on it.

Vista actully purs in 64 I only got a gig yes I ran it it was buggy os loader for some odd reason kept messing up I also got xp64 and 2k3 64.

Now with random lock ups it could also be power supply depending on how old the machine is ram is faulty , hard drive fragemented buggy driver etc etc.

I hear ya ...any pwr supply under 450 nowadays is almost worthless..major cause of failures and hard to diagnose for most..all the new cheap Vid cards are creating problems to.

Yeah that some of thease cases they put in pws that are biggest pieces of junk in the world. That's another thing i thought of bios setting that is off

Yeh..but i,d hesitate to tell a newbie to go in there..ya know?? Could be a bad deal..LOL***

Yeah ur right on that most of the bios/cmos has a restore default option luckly. Sorry about the misunderstanding on the ram eailer i thought you were talking about the net lag.

BTW ..i,m sure not looking forward to taking VISTA apart and tweaking it for 3 months just to get it to run right...lmao****

Triplate · Post by **Triplate** » Wed Mar 22, 2006 11:45 pm

No worries ..have you noticed the inconsistancy of Comcasts network lately??..its bad out here..10 one day..8 the next...but the bill always shows up on time..lol*

I'm being honest you don't need to tweak in my expirence with everything was snappier it's just what I said about the boot loader i'm not sure after i instlled it the boot loader would just go south it could be i need to keep vista on a seperate drive then the other two 0s's.

The install of vista is nice too only have click next 2 then the rest is automated.

Triplate · Post by **Triplate** » Thu Mar 23, 2006 8:19 am

No No..if its not broke..Tweak it till it is..then back off 2 clicks...lol**
