Update:

Have made a few changes to help with the DB load during peak times.
  • Coped the huge 7 GB man page table over to another DB.
  • Moved three busy man page DB queries over to the new database and off the main forum DB.
  • On the last man page table still in use in the main DB, added some code to stop man pages from being served from the DB when the load is very high (serve from a unix command line function versus the DB).

Let's see today if things improve or not, today.

TODO:
  1. Test current code and config.
  2. Move the main man page DB query off the main forum DB and to the new DB.
  3. Delete the man page table from the main DB (when all is tested and done).
