Subject [jira] [Updated] (JCR-3117) Stats for the PersistenceManager
Date Mon, 17 Oct 2011 15:20:10 GMT

     [ https://issues.apache.org/jira/browse/JCR-3117?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex Parvulescu updated JCR-3117:
---------------------------------

    Description: 
Statistics for the PersistenceManager impl that cover: 
 - bundle cache access count, 
 - bundle cache miss count, 
 - bundle cache miss avg duration (this avg includes the penalty of having to load from the
underlying storage / can be interpreted as avg read latency as there is no cache involved)

 - bundle writes per second

What it doesn't cover is :
 - number of bundles
 - size of workspace
as these are values that are expensive to compute on demand, and caching them would imply
being able to store the values (which is not possible currently).
       Priority: Minor  (was: Major)
