This does not result in any issues because of the > full key comparison which is done after the load-acquire of the key_index. > Performance improvements: > Lookup Hit: 6.16% > Lookup Miss: 8.54% > > The second patch in this series, moves the store-release of pData before the > store to any hash internal data structures. This is not necessary, but just > helps to show the non-dependency between application data and hash table > data. On the reader side, the pData is loaded only if the keys match, this > provides performance benefits. > Performance improvements (with patch 1): > Lookup Hit: 6.25% > Lookup Miss: 13.97% Could you share the commands/data to test this specific performance measurement?
