We are using the PostgreSQL currently to store the Bayes information. It
seems to periodically spend a lot of time 'vacumming' which of course
drives up disk load. The system admin has adjusted it so it only does
this at low load. I'm curious if anyone has actually tested the
PostgreSQL vs MySQL versions. We are currently running a uniprocessor
system (Linux version 2.6.18-6-vserver-amd64 (Debian 2.6.18.dfsg.1-24).
System appears disk limited, we have the files on hardware raid 0 and have
moved nearly everything else off that set (they are the fastest drives).
Just curious. Thanks.
