Hi, I changed the subject because with the old one (org.apache.excalibur.store.impl.MRUMemoryStore) I didn't get any response :-( Vadim any comments?
Volker Hi, org.apache.excalibur.store.impl.MRUMemoryStore should lookup "Store.PERSISTENT_STORE" only if "use-persistent-cache" (m_persistent) is true, instead you allways need to configure a persistent store if you use MRUMemoryStore. MRUMemoryStore internal uses a HashMap and a LinkedList. This implementation doesn't scale very well. My proposal is using org.apache.commons.collections.LRUMap instead which will improve performance. Some time ago Vadim has committed MRUMemoryStore into the deprecated block of cocoon (package org.apache.cocoon.components.store). This scales much better in multithreaded environments because the methods aren't synchronized anymore. Internal a "org.apache.cocoon.util.MRUBucketMap" is used. So my question is, why don't we use this implementation, to make Cocoon more scalable? ;-) Volker
