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 :-) > > > John > -- > Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn >
