This is a red herring. 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.

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

I've found iperf to be more useful.
