Nice!
You may still need to use the lock even for the simple unbounded case though - incrementing hits and misses isn't atomic, so the statistics may be miscounted if you get a hit or miss in different threads at the same time.
Alternatively, we could just document the hit/miss statistics as approximate figures for tuning purposes rather than guaranteeing 100% accuracy in all situations. |
