Maurizio Cucchiara commented on OGNL-20: ---------------------------------------- I'm sorry for the missing announce. In my defense I can say that yesterday I have encountered some problems with upgrading of my ubuntu distro. So I was in a kind of hurry and overall scared to lost everything. {quote} Minor question: can I merge now the performances tests in the current /trunk? {quote} Sure, you can. > 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 > Assignee: Maurizio Cucchiara > Attachments: Bench Results.txt, Caching_Mechanism_Benchmarks.patch > > > 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.
