Hello,
  
  On Vmware Fusion (tested with Fusion 1.1 on a Core2duo imac), OpenBSD
(-current) is very slow on anything that is not just a pure computation task.

  While compiling something, or while running MySQL, PgSQL, Apache or
Sendmail, "top" always shows that the CPU spends 99% or 100% of its time in
the system state.

  This is of course with the vic(4) and mpi(4) drivers. But this is always
the case anyway, even without any disk or network I/O.

  Does anyone know what might be wrong?

  Best regards,
  
     -Frank.
