Oh boy. Something tells me you haven't had your hands in the
Informix DSA code as much as I have. The threads scheduler in
that database server was anything BUT "simple time-sharing
round-robin threads". It was a brilliant database-smart scheduler
and as long as it ran on a good OS, you very seldon saw more than
5% of your processor cycles lost to kernel mode...and that
even at extremely high IO rates.
