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. Eugene Grosbein
