Maurizio Cucchiara updated OGNL-20: ----------------------------------- Comment: was deleted (was: Good Morning Julien, It would be very very appreciated. TIA) > Performance - Replace synchronized blocks with ReentrantReadWriteLock > --------------------------------------------------------------------- > > Key: OGNL-20 > URL: https://issues.apache.org/jira/browse/OGNL-20 > Project: OGNL > Issue Type: Improvement > Environment: ALL > Reporter: Greg Lively > > I've noticed a lot of synchronized blocks of code in OGNL. For the most part, > these synchronized blocks are controlling access to HashMaps, etc. I believe > this could be done far better using ReentrantReadWriteLocks. > ReentrantReadWriteLock allows unlimited concurrent access, and single threads > only for writes. Perfect in an environment where the ratio of reads is far > higher than writes; which is typically the scenario for caching. Plus the > access control can be tuned for reads and writes; not just a big > synchronized{} wrapping a bunch of code. -- This message is automatically generated by JIRA.
