- mbell 10y agoI have the same effect on my machine. My guess is that since the L3 cache is shared between cores space used by processes running on other cores is causing a bit of 'blurring' of the performance on the boundary based on how much will data will fit.
- awirth 10y agoI think it's this too. The L3 cache seems to be consistently harder to measure than the L1 or L2 caches. I suspect it's just noise from other cores, but I have no strong evidence to support that.
