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. [1] https://issues.jboss.org/browse/ISPN-3821
* 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.
Looks good
The fix for this bug is now generally released and available here: https://access.redhat.com/site/documentation/en-US/Red_Hat_JBoss_Data_Grid/6.2/index.html
