It appears you are using your database as a clientstore. Is
the application(s) using the same datasource for both client data
and application data? If so, consider separate DSNs (even if they
point to the same db). Also, make sure your application is really
using client data. I have seen many applications set up client
variables and then they are never used. Yet, turning on client
variables and storing them in a database means there is a DB read
for the start of every request and a DB write for every request at
page end. You can limit the writes by setting 'disable global
updates' true in the advanced properties of you clientstore. That
way writes only occur if a true update has been made to one of your
client vars.
If you use one clientstore for many busy applications,
consider dividing it up into several databases and
datasources.
