The good news is that the scheduler is now running as a fast cgi which means it maintains a persistent connection to the DB. The load on the scheduling server has gone way down which is a good thing and the mysql server is using more CPU which is also a good thing. The bad news is that the transitioner is still way behind and so the project will probably run out of send-able work as early as 04:00 UT tomorrow. The transitioner is slow because the mysql server is IO bound. We are having Sun look at our IO system to see if it can be tuned to better performance. At the same time we are planning on moving the physical DB to a high performance Snap Appliance box in the near future. So we are hopeful that these IO problems can be solved.
