So I think these 2 counters should have similar number, but they are NOT, the refill event is double number of miss_rd event! My questions are: 1.

WebJan 17, 2024 · So the rest of the cache accesses would contribute to cache misses, which is the 18.24. If you combine these two number, you get ~5.7, that means 1 cache line fill from either prefetch or cache miss refill every 5.7 loop instances. And 5.7 loop instances needs 5.7 x 3 x 4 = 68B, more or less consistent with the cache line size. WebSubsequent queries against the cache (raycasts, overlaps, sweeps, forEach) will refill the cache automatically using the same volume if the scene query subsystem has been updated since the last fill. ...
