hi, I am porting this patch "zram: user per-cpu compression streams" (https://patchwork.kernel.org/patch/8971921/) back to my arm64cpu/1G memory hardware. On original version, all cpus use one zram compress stream while swapping out. After patch every cpu has a compress stream. I did get a nice look result with fio test, but with a monkey-like test, it is not as good. Maybe L2 cpu cache caused this issue? How can i find out what caused this issue?
