Re: Urgent: Tuning strategies?

I'll add one more observation here:

Everyone else already mentioned the shared mem and sort mem, but I've
found that while increasing wal_buffers and wal_files helps, 64 WAL files
is probably overkill.

I'd suggest the strategy to take your postgresql.conf file to stock, run a
dozen or so slow queries at once, then make ONE CHANGE at a time and see
how much of a difference it makes.

And remember, just because a little helps does NOT mean a lot will. Often
it's the first change that makes the biggest difference.
