I can't find it, where is the file to download?

Version 3 is here http://testmy.net/forum/index.php?action=dlattach;topic=1013.0;id=550

You already made a new one?
You know im trying it ;)

Nice
Now I just have to wait for some songs to finish dling so I can reboot

thanks for the feedback ddriesse

I have reduced the TCP windowsize and GlobalMaxTcpWindowsize to fit most ppl, but there will always need some finetuning, and if i receive more ppl on 5 Mbps package reporting this i will change it again

to finetune that check this guide http://thegamer.serveftp.com/FAQ.htm

start here " 25. Run this TCP analyzer http://forums.[this.site.has.been.blocked.for.spamming]:8117/ "

ah you not using windows XP SP2

the Cabletweaks are made for SP2, i should have added that

check these steps http://testmy.net/topic-2097

if you using this file

C:\Program\Cablenut\VanBurens_cablenut_settings_version_4\vanburens_cablenut_settings_version_CABLE_FIBER_DIAL-UP\WinXP_2K_CABLE_DSL\MSS1460

Cable & DSL 5000 768.ccs

that file has a DefaultRecivewindow of  624640 and thats the value you should see in that analyzer with SP2 installed

and the tcp analyzer says you have 64240

thats typical for ppl that dosent have SP2 installed, cos they read the TcpWindowsize and not DefaultReceivewindow

so something is way wrong on your end, cos the Analyzer works great.

its reporing my DefaultReceivewindow and not TcpWindowSize...

TCP options string = 020405b40103030301010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 384000
RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
Unscaled Receive Window = 48000

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
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
 64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 15360 Kbps (1920 KBytes/s) @ 200ms
Your RcvWindow limits you to: 6144 Kbps (768 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 51 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00110000

Precedence (priority) = 000 (routine)
Delay = 0 (normal delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 0 (normal cost)


and my TcpWindowSize is 64240
