The problem is probably file I/O. I use samba for use with Windows. I can transfer a large file from my FreeBSD server and get almost 10MB/s (using an Intel 10/100 card). However, when I transfer files to FreeBSD, I only get about 6MB/s. I seem to get this same ratio when using FTP transfers as well. This leads me to believe it is I/O bound (my FreeBSD machine has a UDMA66, mainboard limitted to UDMA33, 7200RPM drive in it running softupdates). BTW -- this is one area where Linux (w / reiserfs) kicks the FreeBSD daemon all over town.
