Parameter Adjustments that Improve TCP/IP on LAN Man (97494)






This article was previously published under Q97494

SUMMARY

If you want to benchmark throughput with TCP/IP on LAN Manager across routers and a link, set the following parameters first to improve performance.

Set a tcpwindowsize larger than default. This is especially important for performance on high-delay links. To achieve the best performance, try a tcpsegmentsize of 1450, and a tcpwindowsize of at least 4350, on both client and server. These values offer a significant improvement over the defaults.
