[jboss-user] [JBossCache] - Re: Jboss cache and heapspace memory

[haribaasha]

One more thing i noticed. i turned off the caccheloader completely, i.e no bdbjeloader. so when the evict is called it is evicted from in-memory. In this case once my operation is complete and eviction happns the jvm comes back to the state before i started. so here are my results :

1. withcacheloader(bdbje) and CustomLRUPolicy(evicts from cache for timetolive, calls remove on Treecache for maxage) -  memory hits very high peak and doesnt come down 1.1G

2. same as 1 only very low time to live, so evict will be called almost instantly , but high max age so the nodes are there in persistent storage - memory usage similar to 1.

3. no cache at all - memory usage is minimum about 100M continously

4. with cache and no cacheloader, hence evicted will be lost - goes up to 800M but on eviction comes down to 100M again.
