It depends on which API you want to measure the performance of. > Is it possible to use any standard tool such as netpipe ? Yes, it should be, if you're using the sockets API. However, the performance of the current implementation of the sockets API is pretty poor - certainly much below the raw API - so I'm not sure it will give you particularly useful numbers. Writing a pair of simple ping-pong (for latency) and streaming (for bandwidth) style test app for the raw API shouldn't take more than a few minutes, and I expect someone has already done so. Perhaps they would like to contribute it back to the "contrib" module if so. Performance will depend very heavily on the hardware you have, and the configuration of lwIP. E.g. how much memory is available for receive packet buffers etc. Kieran _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users
