CacheManager interval between recalculation of cache sizes should be
configurable
---------------------------------------------------------------------------------
Key: JCR-1112
URL: https://issues.apache.org/jira/browse/JCR-1112
Project: Jackrabbit
Issue Type: New Feature
Components: core
Affects Versions: 1.4
Reporter: Przemo Pakulski
Priority: Minor
Currently interval between recaluclation of cahce size is hard coded to 1000
ms. Resizing/recalculation of cache size is quite expensive method (especially
getMemoryUsed on MLRUItemStateCache is time consuming)
Depending on the configuration, we realized that under some load up to 10-15%
percent of CPU time (profiler metrics) could be spend doing such
recalculations. It does not seem to be needed to resize cache every second.
Best this interval should be configurable in external config. file with other
cache settings (like memory sizes).
