This is not part of your config, if you read the name of the box it is
in on the System Configuration page, it is a Global Attribute.  It
tells RT when to flush the cache of Queues that a user sees (because
something has changed).

I find it doubtful that this is relevant to your performance problems.

Your admins can turn on StatementLog by setting it to 1 and looking
in the web UI to get a sense of what queries are running on particular
pages.  They can also enable MasonX::Profiler as documented in
RT_Config.pm to see what parts of a page are specifically slow.

Both of these should be done on a development server.
