The slowdown during start up appears to be in biowr; this is probably
because of IDE write caching being switched off. More seriously

Write caching is incompaible with soft updates.

Hi,
I'm wondering what's changed recently to cause vmware2 running on
the linuxemu to lose a lot of performance with disk I/O.
A couple of weeks ago I could boot win2000 under vmware2 in a matter
of minutes; on today's kernel it takes 5 or 10 minutes to boot,
and disk I/O is through the roof.
