Hi,
I've read this:
http://wiki.postgresql.org/wiki/Prioritizing_databases_by_separating_into_multiple_clusters
But it doesn't really say anything about memory.
If i can fit an extra cluster into it's shared buffer, it should have fast
reads, right?
Even if i don't have seperate spindles and the disks are busy.
This is on a Debain server, postgres 8.4
Cheers,
WBL
