--- Comment #2 from Sebastian Lackner <sebastian at fds-team.de> ---
I would like to point out the following wine-devel discussion about the same
topic:
http://www.winehq.org/pipermail/wine-devel/2014-April/104088.html

Especially this comment by

* Vincent Povirk, that exaplains why it is so difficult to optimize the speed
of SetEvent/WaitForMultipleObjects:
http://www.winehq.org/pipermail/wine-devel/2014-April/104090.html

* and this comment by me, which explains the differences between the different
sets of synchronization primitives:
http://www.winehq.org/pipermail/wine-devel/2014-April/104092.html

At my opinion its very difficult to optimize the speed of these specific
functions, but as Bruno already wrote, some (minimal) test code would probably
be useful - especially to measure how "bad" the performance really is compared
to Windows.
