This appears to be one of those questions that is best answered by testing. 25k is not a lot of records or nodes, per se, but it is hard to predict potential pitfalls that one might encounter in a specific Drupal configuration. Since this is not so big that it wouldn't run on almost anything, why not copy your site onto a dev server - your laptop, perhaps - and give it a try. Even if it fails, it might give you some insight as to what workaround is required.
