I get 20.94MB/sec in parallels with Fedora Core 4.
Turning DMA on in Parallels ups me to 35.89MB/sec
Cached reads show 1440.06 MB/sec in Parallels though so I have no idea
what the heck it's really measuring :-)
At any rate, I'm getting along fine with virtualized OSes and almost
never expect amazing performance from Plan 9 compared to Linux and
other OSes.
In fact, I'd say performance of "good enough" is often just that for
my home use.
I'm not one of those gentoo people :-)
