In-Depth Information
Performance testing has shown that disabling
Capture Com-
posite Instance State
results in, on average, a performance
improvement of 24 percent of your composite instances.
By default, audit data is logged to the database synchronously. This means that
instances will remain active until the audit information is committed to the data-
base. This does not perform ideally under load. By switching the audit policy to
deferred
, all audit operations are invoked asynchronously, resulting in perform-
ance comparable to setting the audit level to
off
. This is huge! Note that
Cap-
ture Composite Instance State
must be disabled when using
deferred
for this
to take effect.
Perhaps the largest composite instance performance gain
can be attained by setting the audit policy to
deferred
, which
results in all audit data being committed to the database asyn-
chronously.
Set composite instance auditing to
deferred
