[Bug 567302] Re: Lucid critical performance regression for Apache and PostgreSQL

Sorry but that Moronix benchmark is worthless.  You can't get 784 tps
using pgbench on a single 7200RPM disk unless your write commit path is
broken.  The Lucid value of ~ 80 tps is much more reasonable and
probably means that something is finally forcing the Moronix test laptop
to commit writes to disk on fsync.  This is not a regression, it's an
improvement.
