WebWith this patch, the swap out bandwidth improved 22.3% (from ~1.2GB/s to ~ 1.48GBps) in the vm-scalability swap-w-seq test case with 8 processes. The test is done on a Xeon E5 v3 system. The swap device used is a RAM simulated PMEM (persistent memory) device. The improvement comes from the reduced contention on the swap cache radix tree lock.
