Thread:Project:Support desk/rev id in revision table is very very loosely packed/reply

What do you mean with "our max(rev_id) is 1.7b"?

You can remove old revisions from the table by using the deleteOldRevisions.php script. However, this will influence page history (as these revisions will then no longer be there). Maybe you could also compress the content in that table, however, this will not reduce the number of rows.

If all doesn't help you can update your links via a cron job, e.g. every Friday at 2 a.m. The performance decrease during that time should not hurt your users much. ;-)
