Speed?
Okay, so I've read all over and I'm just not coming up with anything that suits my connection. My caps are 3500/384 on Comcast Pro, using Win2000 SP3, 551MHz PIII, 512MB RAM, 20GB HDD, etc.. Here are the results of the TCP Optimizer test (FYI, I'm using Lobo's CableNut settings):
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.0.3705)
TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
RWIN is 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)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 50 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
So what can I do to speed this up, if anything?
Thanks.

What am I looking for here? These tweaks all appear to be XP related, and I am on Win2K SP3.Originally posted by Hybridmonolith

Also read the Help & Tips link in my signature and try the other suggestions.

how much $$$?
How much does it cost per month for those kinda caps anyway? and is it cable modem?
speed
joecool169
that guy was getting 340 KB/sec and you told him that was 90% of his cap?
340x8=2720 wich isnt even close to 90% of his cap
3150 is 90% of his cap
2720 and 3150 is alot of differance my friend 430 differance
he is at 78% of his caps
not trying to be rude just telling you he should be able to get another 400 or more then he is getting now with the right settings wich is alot its a additonal 50 KB/Sec

dont you agree that he should get better then 2700 on a 3500 line?
