I use the MySQL Tools to handle compacting and repair etc. For other jobs I use DBTools. Neither is perfect, but between them they get the job done. I do most of my admin from windows but afaik the MySQL tools are cross platform. Despite the above, I was (perhaps mistakenly) under the impression that the daily admin for bayes handled compaction etc. Perhaps your problem lies elsewhere in your system? I know form ages back that lack of a PTR for the SQL server can slow things significantly if your DB is on a different box to your SA. HTH Nigel
