This will provide quite a major performance boost by avoiding synchronizing on EVERY chunk lookup. Synchronize, even without contention, incurs processor cache flushes. Considering this is the 2nd hottest method in the code base, lets avoid doing that... Additionally, chunk conversion operations were occuring while under synchronization which lead to deadlocks. Now the conversion will occur outside of the lock, and fix that issue, resolving #1586 Note, that the chunk map is still thread safe for get operations! The chunk map was never intended to be modified async with our changes, as we post to main to modify the map, however we do still synchronize for write operations (put, remove) We also synchronize for async get operations, ensuring that async gets are safe. We do not need to synchronize main thread gets as the processor cache will be insync since the map is only updated on the main thread. However, if someone does try to delete or put concurrently, we will force their operation back to the main thread. |
