Need some help heres my settings.

Kith · Post by **Kith** » Sat Sep 07, 2002 5:13 pm

Here are all my settings right now. My cap is 1500 and i am only getting 1300 i know i can get way closer, so please help me out. Oh also forgot to mention, i am useing Windows Xp

In Cablenut.

DefaultReceiveWindow=3584000
DefaultSendWindow=385024
DisableaddressSharing=1
InitialLargeBufferCount=1000
InitialMediumBufferCount=3000
InitialSmallBufferCount=5000
LargeBufferSize=81920
MaxFastTransmit=6400
MediumBufferSize=15040
PriorityBoost=0
SmallBufferSize=64240
TransmitWorker=32
FastSendDatagramThreshold=9216
EnableFastRouteUp=1
EnablePMTUDiscovery=1
IgnorePushBitOnReceives=0
GlobalmaxTcpWindowSize=3584000
MaxFreeTcbs= 8000
MaxHashTableSize=3200
MaxNormLookupMemory=5000000
SackOpts=1
SynAttackProtect =1
Tcp1323Opts =1
TcpLogLevel =1
TcpMaxDupAcks =2
TcpMaxHalfOpen =100
TcpMaxHalfRetried =80
TcpRecvSegmentSize=1460
TcpSendSegmentSize=1460
TcpTimedWaitDelay=30
TcpUseRFC1122UrgentPointer=0
TcpWindowSize=3584000
MaxConnectionsPer1_0Server=40
MaxConnectionsPerServer=20
DefaultTTL=128
DisableTOSUserSetting=0
TcpMaxDataRetransmissions =6
DefaultTOSValue=92

In the regisrty

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic

es\AFD\Parameters] Added DWORD BufferMultiplier=6 (Decimal)

I have done the NIC card buffer tweak.. 7168

Here is my Analyzer resaults:

TCP options string = 020405b40103030601010402

MTU = 1500
MTU is fully optimized for broadband.

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

Default Receive Window (RWIN) = 3584000
RWIN Scaling (RFC1323) = 6 bits
Unscaled Receive Window = 56000
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN 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)

bandwidth * delay product:
Your RcvWindow limits you to: 143360 kbps (17920 KBytes/s) @ 200ms
Your RcvWindow limits you to: 57344 kbps (7168 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 121 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 01011100
Precedence (priority) = 010 (immediate)
Delay = 1 (low delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 0 (normal cost)

- Thanks in advanced!

Those settings cause quite a stir around here but, I use them and get full speed out of my connection, The only difference is that i have the BufferMultiplier = 7168 Hex,.

Just remember to always back up your REG and Settings.

But with your Caps try these in Cablenut, ( I know people are gonna jump all over these settings but it don't hurt to try. Backup.

DefaultReceiveWindow=1536000
DefaultSendWindow=131072
DisableaddressSharing=1
InitialLargeBufferCount=1000
InitialMediumBufferCount=3000
InitialSmallBufferCount=5000
LargeBufferSize=81920
MaxFastTransmit=6400
MediumBufferSize=15040
PriorityBoost=0
SmallBufferSize=64240
TransmitWorker=32
FastSendDatagramThreshold=9216
EnableFastRouteUp=1
EnablePMTUDiscovery=1
IgnorePushBitOnReceives=0
GlobalmaxTcpWindowSize=1536000
MaxFreeTcbs= 8000
MaxHashTableSize=3200
MaxNormLookupMemory=5000000
SackOpts=1
SynAttackProtect =1
Tcp1323Opts =1
TcpLogLevel =1
TcpMaxDupAcks =2
TcpMaxHalfOpen =100
TcpMaxHalfRetried =80
TcpRecvSegmentSize=1460
TcpSendSegmentSize=1460
TcpTimedWaitDelay=30
TcpUseRFC1122UrgentPointer=0
TcpWindowSize=1536000
MaxConnectionsPer1_0Server=40
MaxConnectionsPerServer=20
DefaultTTL=128
DisableTOSUserSetting=0
TcpMaxDataRetransmissions =6
DefaultTOSValue=92

Let me know how they worked.

Try:

DefaultReceiveWindow=192000
DefaultSendWindow= your upload cap / 8 * 1024
DisableaddressSharing=1
InitialLargeBufferCount=1000
InitialMediumBufferCount=3000
InitialSmallBufferCount=5000
LargeBufferSize=32768
MaxFastTransmit=64
MediumBufferSize=15040
PriorityBoost=0
SmallBufferSize=429
TransmitWorker=32
FastSendDatagramThreshold=8760
EnableFastRouteUp=1
EnablePMTUDiscovery=1
IgnorePushBitOnReceives=0
GlobalmaxTcpWindowSize=64240
MaxFreeTcbs= 164
MaxHashTableSize=92
MaxNormLookupMemory=5000000
SackOpts=1
SynAttackProtect =1
Tcp1323Opts =1
TcpLogLevel =1
TcpMaxDupAcks =2
TcpMaxHalfOpen =100
TcpMaxHalfRetried =80
TcpRecvSegmentSize=1460
TcpSendSegmentSize=1460
TcpTimedWaitDelay=30
TcpUseRFC1122UrgentPointer=0
TcpWindowSize=64240
MaxConnectionsPer1_0Server=40
MaxConnectionsPerServer=20
DefaultTTL=64
DisableTOSUserSetting=0
TcpMaxDataRetransmissions =6
DefaultTOSValue=92

Sorry if it slows you down, just revert back to your old settings. I don't have you connection so....

Alrighty will test this =D

The GlobalmaxTcpWindowSize will override the Rwin.

Errr isn't it the GlobalmaxTcpWindowSize will override TcpWindowSize

I need a second opinion.

Oh also, my cable provider doesn't say a certain speed advertised. They just say 50x faster then 56k but i don't thikn its 56k so i am guessin my cap is arond 1500

SICMF · Post by **SICMF** » Sat Sep 07, 2002 7:19 pm

Did you try any of these settings yet?

I think they says "50 times faster than dial-up" right? Well its 50 x 28.8

Trying Hybrid's now

Kith · Post by **Kith** » Sat Sep 07, 2002 8:39 pm

With Hybrids, my caps are hitting 1418ish, going to try mohans now

Kith · Post by **Kith** » Sat Sep 07, 2002 8:45 pm

With Mohan its about 1410-1416 lil lower the hybirds, this is weird to me since there numbers are totaly differnt. Think i can get higher then Hybirds with 1418?

Run with them for a while, Test your speeds later when the web dies down a little, Thats a nice number considering your caps.

Kith · Post by **Kith** » Sat Sep 07, 2002 8:53 pm

Weird, i have been trying a few differnt testing sites, there about the same yours and mohans. I don't see how it makes sense but oh well hehe. Now only if i could get linux not to hang and say i don't enough of disk space problem fixed!

Anything else i can do to get closer to my cap

SICMF · Post by **SICMF** » Sat Sep 07, 2002 10:19 pm

What value do you have for your BufferMultiplier?

Mohan-san · Post by **Mohan-san** » Sun Sep 08, 2002 5:26 am

Your pretty close to your caps. About 94%. Thats excellent.

Kith · Post by **Kith** » Sun Sep 08, 2002 12:14 pm

6 is the BufferMultiplier

Mohan-san · Post by **Mohan-san** » Sun Sep 08, 2002 12:57 pm

Ok try 7168 or 1024 decimal.

SICMF · Post by **SICMF** » Sun Sep 08, 2002 1:30 pm

7168 Hex, decimal is way to high.

Kith · Post by **Kith** » Sun Sep 08, 2002 1:45 pm

Soo what should i try then.. btw i was alil wrong with Hybirds and Mohans it ranges from 1397-1428ish

I'm using 7168 Hex, and webpages scream and my downloads are great. Give that a shot.
