Features are: - multiple TCP connections, - auto reconnect if a connection breaks, - it writes statistics to several files that can be easily visualized with gnuplot. Compile it with the Glasgow Haskell Compiler (GHC): ghc -O2 -o netperf Main.hs On the first host with ip_addr_1 run: ./netperf 4 6000 ip_addr_2 6000 On the second host with ip_addr_2 run: ./netperf 4 6000 ip_addr_1 6000
