Replace lock-based stats with Interlocked in MemoryPluginCache#37
Merged
Conversation
Using Interlocked.Increment/Read instead of lock(_statsLock) removes unnecessary contention on the hot path. Cache hit/miss counters are simple atomic increments that don't need mutual exclusion with other state.

Straightforward improvement. The Interlocked operations are correct here since hits and misses are independent counters - no need for compound atomicity.

Problem:
MemoryPluginCacheuseslock(_statsLock)for simple counter increments on the cache hit/miss hot path. This creates unnecessary contention when multiple threads access the cache concurrently.Solution: Replace
lockblocks withInterlocked.Incrementfor counter updates andInterlocked.Readfor statistics retrieval. Remove the_statsLockobject entirely.This is a zero-allocation, lock-free improvement that reduces contention without changing behavior.
