We found this patch helps much for swap out performance, where there are
usually only one mapping for all swap pages. In our 16 processes
sequential swap write test case for a ramdisk on a Xeon E5 v3 machine,
the swap out throughput improved 40.4%, from ~0.97GB/s to ~1.36GB/s.
What's your plan for this patch? If it can be merged soon, that will be
great!
I found some issues in the original patch to work with swap cache. Below
is my fixes to make it work for swap cache.
Best Regards,
Huang, Ying
