I took a quick look at your xperf program source code, and noticed you 
use XSync, try replacing that with XFlush.

XSync is much slower and it might well be that the newer Xorg version 
tries harder to make sure really all X-protocol state has been 
processed, thus being even slower.

XFlush should be sufficient for your test.
