Comment on Redis latency spikes and the Linux kernel: a few more detailsparentComments−daviesliu11yCould your confirm that the MOV is copying PTEs? I doubt that maybe it's copying the heap, because of copy-on-write. After fork(), the parent write to heap randomly, so it will copy more data with jemalloc than libc (because of huge page)
