postgres runs just fine, withou any special tuning. granted i'm not doing
any large number of transactions (a few thousand/hour), but i'm not seeing
the problems that you're describing. which UML kernel are you running,
and what kernel are you running on the host? I'm using 2.4.19 on both
host & UML, with SKAS.
