WebOn almost all modern x86 CPUs (both Intel and AMD), it's impossible to have data in the L2 cache instead of the L3 cache. That would cause cache coherency to fail because the absence of data in the L3 cache signals its absence in the L2 caches and permits a core to assume no other core has cached it. WebOct 2, 2024 · The performance difference can be significantly reduced if the L2 cache is not set large enough. We created five test cases, using FIO to measure IOs per second and average latency of IOs. The default L2 cache size is used in all five tests: 100 GiB virtual disk with 256 KiB cluster size 100 GiB virtual disk with 512 KiB cluster size
