comment FreeBSD Host ZFS on Root Running VirtualBox with Windows Server 2003 Guests Very Slow HD Speeds
I checked the ports and it is only 4.0.14 for Virtualbox. I haven't attempted to compile from source yet, but probably should. I choose FreeBSD 7 over 9 because a good friend and FreeBSD enthusiast told me that setting up ZFS on root would be much easier on 7, and after a few failed attempts at 9, he was correct. The only adapter type I haven't tried is the SCSI type. The other 2 didn't make a difference.

comment FreeBSD Host ZFS on Root Running VirtualBox with Windows Server 2003 Guests Very Slow HD Speeds
I did some benchmarking and got some crazy results. Using CrystalDiskMark 3.0.1, on SEQ I get 229.1 MB/s Read and 168.5 Write. On 512K I get nearly the same. On 4K I get 11.56 MB/s Read and 11.07 MB/s write. I believe this points directly to the problem. On small files the read and write goes to crap. Is there any tuning I can do to improve this performance?
