I agree with Jerry also.  If you have the disk to burn, cacheing doesn't
really cost you anything.  It may not buy you very much, depending on your
particular situation, but since it doesn't really cost you much then I think
it's worth doing.

One other (very minor) negative is that since cacheing will slightly
increase the size of your database, then database backups will also take
slightly longer to run.  The difference is probably not worth worrying about.
