If not, consider raising MTU to 1500 for optimal throughput. MSS = 1452 MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value. Default TCP Receive Window (RWIN) = 65535 RWIN Scaling (RFC1323) = 0 bits Unscaled TCP Receive Window = 65535 Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). For optimum performance, consider changing RWIN to a multiple of MSS. Other RWIN values that might work well with your current MTU/MSS: 63888 (up to 2 Mbit lines, depending on latency. MSS * 44) 127776 (1-5 Mbit lines, depending on latency. MSS * 44 * 2) 255552 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2) 511104 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3) 1022208 (25-60 Mbit lines depending on latency. MSS * 44 * 2^4) bandwidth * delay product (Note this is not a speed test): Your TCP Window limits you to: 2621 Kbps (328 KBytes/s) @ 200ms Your TCP Window limits you to: 1049 Kbps (131 KBytes/s) @ 500ms MTU Discovery (RFC1191) = ON Time to live left = 107 hops TTL value is ok. Timestamps (RFC1323) = OFF Selective Acknowledgements (RFC2018) = ON IP type of service field (RFC1349) = 00000000 (0) Quote Link to comment Share on other sites More sharing options...
