I've been testing FreeBSD 8 at work to determine viability for replacing our current FreeBSD 7.2 server. I encountered similar issues to you khakkinen in terms of network performance.

Mine are running as guests under VMware ESXi 4 Update 1. My biggest issues has been disk I/O performance, but that seems to be regardless of which version of FreeBSD I'm running. I benchmarked each system using NUTTCP (network) and DD (disk).

My results averaged the following:

FreeBSD 7.2
  • 900Mbit/s network throughput
  • 14MB/s disk transfer speed

FreeBSD 8.0
  • 500Mbit/s network throughput
  • 11MB/s disk transfer speed


My network performance is down by a huge 45% and my already crippled disk performance is down another 20%. I've tried various tweaks (I was going to link you the tweaks I used, but apparently I'm not allowed) to improve performance, but it doesn't seem to make any difference.
