Lazily ressurect ice fromMemory ------------------------------- Key: ISPN-8517 URL: https://issues.jboss.org/browse/ISPN-8517 Project: Infinispan Issue Type: Sub-task Components: Off Heap Affects Versions: 9.2.0.Alpha2 Reporter: William Burns Assignee: William Burns Fix For: 9.2.0.Beta2, 9.1.3.Final Currently many places do {code} ice = ice = offHeapEntryFactory.fromMemory(address) if (wrappedKey.equalsWrappedBytes(ice.getKey())) {code} In cases where this ends up being a miss, we read the entire value which is wasteful. And the CPU may not have the key in the cache size we read the object into memory. Where as if we do {code} if (offHeapEntryFactory.equalsKey(address, key)) ice = ice = offHeapEntryFactory.fromMemory(address) {code} we know that CPU is reading from the address location twice in a row, which has a very high chance of still being in CPU caches which should hopefully provide better performance. We also then don't have to read the entire ice object in memory unless there was a hit. We also should change _performGet_ to return the address instead of the ice. This way callers can use this address for other optimizations such as when doing a _evict_ or _compute_ which have to read the entry first before a remove.
