Description gsheldon 2013-12-13 01:05:51 UTC

From Tristan:

the EAP performance team discovered that enabling statistics adversely
affects performance. Unfortunately the current upstream Infinispan
subsystem enables them by default, so I've created an issue [1] and
patch to add an optional boolean "statistics" attribute to the
<container> and <*-cache> elements.
For compatibility reasons, statistics will stay enabled for this version
of JDG, but we plan to disable them by default in the next version.

Comment 2 gsheldon 2013-12-16 07:37:01 UTC

* add an explicit statistics="true" attribute (which also happens to be the default) so that users are aware that such an attribute exists.

* add a paragraph to that topic (and other related ones) pointing out what
the attribute does and possibly referring to the more generic statistics
chapter. 

* In the Statistics chapter add a paragraph explicitly stating that
enabling statistics has a performance impact.
