Hi!

Is it possible to saturate 100Mbit ethernet using FreeBSD 4.9-STABLE,
Pentium-133 & Intel 430VX-based motherboard (PCI-33),
Intel 82559 Pro/100 Ethernet (fxp) ? 

I tried to use sendfile(2) on /dev/zero but that does not work.
Then I created 8Tb holey file and used sendfile() on it.
That gave 100% CPU load and only 37Mbit/s on wire.
