Jason,

Thanks. Now, in order to be perfectly clear, let me pose an example. If I
ask for a Web page that sends back, for example, an html table based on a
data grid that is limited to 8 rows of data from a 500-row table, what data
are cached, the 8 rows, or the entire table?

MSSQL latest versions have a feature to cache "results" and re-uses them
if
it can, e.g. multiple users posting the same SQL.

IB / FB does not cache results ever. It does however cache the raw data
that was used to generate the results, i.e. data pages from disk. The
obviously cache's disk reads also.

I don't think you should change IB/FB's cache settings as this may
adversely
affect normal operation.

When we do testing we have a ground zero state, it may be a fresh boot of
the OS, it may be a a restart of the FB service, depends on what we are
doing.
