My last words on the performance issues;

The rule of that I live by is " Watch your Seizes, Locks, and DB I/O's
and the nanoseconds will take care of them selves"

Do whats right,  The machine will catch up.  example; We're putting all
Date, Time, Timestamps in all DB files.  The Processing will get faster
as time goes on but your stuck with a bad design decision for EVERRRRRR.
