I have compared the staff with an all-in patch (contains all changes from these
patches) against r46520. I used the _localized_ version of the stress test what
I attached (every picture was downloaded, the urls were changed to the local
files). I measured the time what is needed for loading the images by the time
command, and I measured the maximum resident set size with getrusage from
<sys/resource.h> on a linux system with a patched kernel what is able to give
this info like BSD-s (with a little hack on QtLauncher). Results:
