vtcp.386 patch

Post by Bigpoppapump »

I just went back to my default settings to start over and I just installed the @home patch only. So I ran the analyzer .........

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) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
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: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 119 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000


The analyzer states that I should install the MS Vtcp386 fix.? I went to Windows\System dir and I do see the vtcp.386 file. Just wondering if the file already in there isnt the patch from SG's page. And if so, when you go back to default settings do you have to install the vtcp386 patch again?

My specs.......
Win98SE
1 gig TBird
256 MB PC133
Cable

Lobo your the local guru with all the magical RWIN's so I'll try all of them. Thx peeps in advanced.
