Right now I get about 90-100kb/sec while downloading from www.netscape.com (was downloading divx movies too, so will try again later). My line is capped at 1mb down. Should I expect anymore?


TCP options string = 020405b40103030301010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 524176
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 65522
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: 20967.04 kbps (2620.88 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8386.816 kbps (1048.352 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)= 00000000

ok go to lobo's help page in my sig

you can't get accurate test speeds when you are dl ing

for best speed results you shoudl defrag and do scandisk, turn off all apps in taskbar. clear temp files then test :)

Lobo's help page tells ya all about it.

Since you are here check out the RamDisk too, you will probably like it a lot, I sure do and I run same OS as you :)

Yeah, will test downloads tomorrow (Downloading The Matrix and Save the Last Dance). Plan on testing a few different RWINS and looking into the RAMDISK. I can see myself redoing my PC a few times trying out the RAMDISK..

do you know how to chang file extensions, that is the only flaw in the whole thing, I told him to put it in but he forgot

as long as you follow the guide and do exactly as it says,(and know how to make file extensions) you cannot mess up it is foolproof :D

look around for someone on 2K with same CPU size and same connection type to see what RWIN they have used and how it worked for them

and there are the suggested RWIN's by the TCP/IP Analyzer too

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)

Have Fun

Was downloading with LimeWire, but gets annoying when stops in middle and won't resume.
