Shouldn't be a big issue - if you have the correct indexes (i.e. all of
your join expressions, order by etc should have an index on them).
10,000 records is pretty small.
This is assuming you're not running on an ancient version of RedHat or
something. MySQL 4 & 5 have had a lot of performance improvements.
