For large catalog, we usually advise to use PostgreSQL where we have multi-terabytes databases in production. > Since upgrading, I lose a few jobs a night due to database locking > timeouts, which I have set to 3600. I also log slow queries. Can you get some information about these locks? On which table? Can you give some statistics on your catalog like the size and the number of records of the File, Filename and Path table? Would be nice also if you can give the number of Filename per Client (from the job table). You might have many orphan Filenames, and MySQL is not always very good to join large tables (it uses nested loops, and cannot use the index on the Text column in all queries). > It appears that typically during a months I have about 90-100 queries > that take longer than 15 minutes to run.

Maybe, but I'm not sure, we did not change a lot of thing in this area, we did mostly refactoring.
