While "big", that's by no means "huge" for MySQL.

Can you talk about what you've done to tune your MySQL server? MySQL
performance tuning can take you a lot larger than you're currently at.
Having enough RAM and _using_ it are both important for keeping mysql
purring.

I know of a VOIP provider with (a locally hacked and improved) RT with
16 million tickets in it, a social network with six million tickets in
their RT (though I haven't ever _talked_ to them about it. just reported
bugs in their site ;) and at least one company running a very stock RT
3.4+ a few custom mysql indexes with well over a million tickets and
pretty impressive performance.
