--------------------------------------
Summary: replace synchronized blocks by java locks or
concurrenhashmap
Key: JCS-119
URL: https://issues.apache.org/jira/browse/JCS-119
Project: Commons JCS
Issue Type: Improvement
Reporter: Romain Manni-Bucau
A cache is typically used in a concurrent environment. Since Java 6 using a
ReentrantLock is faster than synchronized so can be interesting to replace
synchronized blocks by a lock.
Places i'm thinking about:
* CompositeCache
* AbstractDoubleLinkedListMemoryCache
* LHMLRUMemoryCache
* DoubleLinkedList
* LRUMap
* SingleLinkedList
* SortedPreferentialArray
Some places where replacing a HashMap by a ConcurrentHashMap can allow to get
rid of synchronized without needing a lock:
* CacheEventQueue
* AbstractDiskCache
* CacheWatchRepairable
There are other places but this is the main I saw.
