In my limited experience with VMWare linux seems to have near bare
metal disk performance. FreeBSD seems to incur a significant
performance penalty. For instance on my laptop, running OSX and
VMWare Fusion, FreeBSd virtual machines can't saturate 100TX off the
disk, raw dd manages about 7 Megs/sec, which is in line with what I
get shovelling big files around. Disk is a 7200 RPM SATA2.
