[x264-devel] Performance difference between windows and linux

[Pradeep Ramachandran]

Hi all,
I notice an ~50% performance difference between windows and linux platforms
on the same hardware (linux is faster) when I encode 4K videos with the
most presets with x264. When I poked further, we notice that the
page-faults in windows are 2-3 orders of magnitude more than on linux, and
this is despite using the VirtualPrefetch() function in x264.

Does anyone have any experience with this that they can share to improve
this?

Pradeep.
