Hi ,

Please tell me how many number of sockets LwIP supports?

I looked into using iperf with lwIP on my embedded system. The crux of the problem is that iperf needs to be compiled for a POSIX environment. You might get it to successfully wrap around lwIP's socket layer, but you'd probably have to modify the iperf configuration files to target your specific environment.

I did not look at netstat.

Needless to say, this was beyond the scope of what I was looking for. In the end, if you have access to the code for your driver, its a fairly simple matter to modify it so that it collects the statistics for you. The driver usually has to parse out the length of packets anyway, so the information you need is already there.

Hi All,

I have just started to have a look to lwIP and I would like to run some performance test to get an idea of the gain.
Can anyone point me to some docs to compile iperf or netstat with IwIP?

Thanks,
MaX
