As far as I know if the hard disk of the guest os is an image file on
the host OS, the host OS treats it as a file and offer to cache it in
the main memory. However if vmplayer access a partition or harddisk it
is not cached by the host OS's file system. That might make it even
slower. Unless of course the database is in particular on a raw device
that is directly accessed from the guest OS, as Sandy pointed out.
The caching doesn't make a difference, as it is not really different.

Lars
