I presume you mean PostGIS tables. For starters, make
sure you have the appropriate indexes created on your
PostGIS table. There are basicallly three indexes to
consider:

- an index on the oid column. this is used internally
by MapServer and PostGIS and makes a HUGE difference.

- a GIST index on the geometry column (probably called
the_geom) is obviously useful, and makes a huge
difference.

- if your layer uses a FILTER to select only certain
records, make sure those columns have indexes

I hope that helps.
