*shrugs*.  Andrew, it will be lost because of the way data is CURRENTLY
saved in the database.  Do you mean to tell me now that if I have a SQL
database, access the database from two applications, and update the
information from one.  Do you want to tell me the information change is not
going to reflect in the second application?  Maybe not if you dont ask for
it again, but SURE the information IS going to be there at the next SELECT
from the database.  Which is more than adequate in the way Services needs to
retrieve its information from the databases.

Once again.  How can you talk about the performance WITHOUT bothering to
test this?  Don't rub of a suggestion / idea just because you are not sure.
I made my first post, I've shown you my results.  I ask again, do you have
similar results for the databases currently in use?  No, I didn't think so.

What we should be focusing on, is to analyse services, and find out EXACTLY
WHAT and WHERE the bottlenecks in services are.  Sure, the databases might
be one of them, but wouldn't it be ALLOT easier if we know WHERE in the
databases the problem lies?  For one, what would happen if you created an
index on the databases for one thing....

bottle neck on the CPU either.  But hey, what do I know...
