I just put together a system with 6GB of ram on a 14 disk raid 10 array.
When I run my usual big painful queries, I get very little to know
memory usage. My production box (raid 5 4GB ram) hovers at 3.9GB used
most of the time. the new devel box sits at around 250MB.
I've switched to an 8.0 system on the new devel box, but the .conf
really didn't change. Index usage is the same. Something seems wrong and
I'm not sure why.
any thoughts,
