Improve the scalability of PreparedQueryCacheImpl
-------------------------------------------------
Key: OPENJPA-1723
URL: https://issues.apache.org/jira/browse/OPENJPA-1723
Project: OpenJPA
Issue Type: Improvement
Affects Versions: 2.0.0, 2.1.0
Reporter: Rick Curtis
Assignee: Rick Curtis
On a large multicore machine (24+cores) there is a large amount of contention
in the PreparedQueryCacheImpl lock.
In this JIRA I'm going to utilize the j.u.c.ReentrantReadWriteLock to improve
read/write throughput.
