I have two machines virtualized under virtualbox.

The first is a FreeBSD 10.3 Machine.

The second is a FreeBSD 11-ALPHA5 Machine


When I run glxgears on 10.3 on the same host normally I get things like 
this:

FreeBSD 10.3
[ota@xareu /usr/home/ota]$ glxgears
871 frames in 5.0 seconds = 174.197 FPS
952 frames in 5.0 seconds = 190.379 FPS
929 frames in 5.0 seconds = 185.777 FPS
614 frames in 5.0 seconds = 122.753 FPS
621 frames in 5.0 seconds = 124.128 FPS
590 frames in 5.0 seconds = 117.913 FPS

FreeBSD11-ALPHA5

[ota@nostromo /usr/home/ota]$ glxgears
562 frames in 5.0 seconds = 112.276 FPS
526 frames in 5.0 seconds = 105.057 FPS
406 frames in 5.0 seconds = 81.167 FPS
404 frames in 5.0 seconds = 80.777 FPS
403 frames in 5.0 seconds = 80.566 FPS
409 frames in 5.0 seconds = 81.601 FPS


All times the 10.3 shows a better FPS.

The 11-ALPHA5 runs on the same hardware (i7), but was compiled on a 
Intel core 2 duo T5300

Can this cause a low performance on Mesa?
