The OP reports he transfers a single file - http server performance cannot even approach to influence the performance in his case (and he's using apache!). There's absolutely no reason to replace apache here. > You can try > 2. increase MTU (ifconfig em0 mtu 65536 or so; never tried that myself) Don't do that. His ifconfig output lists his card doesn't support jumbo frames, and most ethernet card's will wedge if you use MTU > 1500, let alone a nonstandard one as 65536. Even in 1999, standard 1500 byte frames could yield 400 Mbit/s (http://sd.wareonearth.com/~phil/jumbo.html) > 3. ports/benchmarks/tcpblast I've found iperf to be more useful.
