Subject [jira] Created: (JCR-2597) JCR query execution is taking long time

JCR query execution is taking long time 

                 Key: JCR-2597
                 URL: https://issues.apache.org/jira/browse/JCR-2597
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: JCR API
    Affects Versions: 1.5.4
            Reporter: sydaiah nallabirudu


I am using the below jcr query to get the results.This query will return approx : 226000 records.

/jcr:root/<node name>/<node name>/<node name>//*[jcr:like(@Title, '%')]order
by @updatedDate descending|#]

This query is taking approx 8 secs to retrun the node results. 

Jackrabbit application is logging the below statements, when query returns large result sets
hits=0 miss=4300000|#]
mem=8186k max=8192k avg=12956 hits=3140478 miss=1159522|#]

Is it meaning that jackrabbit is caching the data in memory and sorting the data.

How can i improve the query performance
