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? Welcome and thank your suggestions ;)
