500mhz 192 mb Ram (Cable) Win98 SE
I Used to get 350 - 400kb/sec Download and 385kbps upload.
Now im not anywhere near it. I get 155kb/sec download and 120kbps.
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) = 481800
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 60225
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)
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: 19272 kbps (2409 KBytes/s) @ 200ms
Your RcvWindow limits you to: 7708.8 kbps (963.6 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)= 01011100
Precedence (priority) = 010 (immediate)
Delay = 1 (low delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 0 (normal cost)
