[infinispan-issues] [JBoss JIRA] (ISPN-10574) Off Heap iteration performance improvements

Off Heap iteration performance improvements ------------------------------------------- Key: ISPN-10574 URL: https://issues.jboss.org/browse/ISPN-10574 Project: Infinispan Issue Type: Enhancement Components: Off Heap Affects Versions: 10.0.0.CR1 Reporter: Will Burns Assignee: Will Burns Priority: Major Fix For: 10.0.0.CR3, 10.0.0.Final When testing out some things it was found that an off heap cache with a single entry compared to an object one takes significantly longer for state transfer. Off Heap can be improved to make iteration faster and thus improve things like state transfer. # Off Heap entries are stored using modulus for locks. This causes iteration to not access entries sequentially as well as having to acquire the same lock many times over. # Off Heap should optimize code paths that can be short circuited (ie. don't create stream if size is 0)
