<pre>I'm running weston under X to test this, and it looks like the number of frames
rendered is about half that of the same code on Xorg.
I was curious about the raw memfd costs, so put together an informative test:
- memfd_create()
- ftruncate(2*page_size)
- mmap()
- page fault all pages
- munmap()
- close()
The cost for all of the above is about .06 msec. So not really that bad.
Interestingly, half of the time is spent on close()!</pre>
