You are right, CPU is maxed with reflect, while gears uses ~30%.
But I got some improvement when upgraded to XFree86-4.3.0 =).
Now I have:
gears - 1050 fps in window, 160 fps fullscreen
reflect - 198 fps in window, 38 fps fullscreen
(Processor is Pentium 4-M 1.4 GHz)
As it seems to be software GL (with reflect at least),
now I have to investigate why so.
