I've been doing more digging. I have verified that indeed the software OpenGL renderer is creating way too much overhead to be useful for the purposes of this testing, even when just running GLXgears. GLXgears is not a particularly good benchmark for use with TCBench, anyhow, because TCBench monitors a small area at the center of the window, and that area falls within the area of solid red on the left-hand gear, so it never changes. However, I did discover that playing the 1920x1080 version of Big Buck Bunny from the beginning using VLC in full-screen mode makes a good 2D benchmark. The beginning of this movie has full-scene motion on almost every frame, so if you start TCBench very soon after starting the movie, you should get a good reading. When I do this, I get 14-15 fps with TLS disabled and 4.5 fps with TLS enabled. In other words, about the same relative difference as I got with GLXspheres and VirtualGL. You should be able to perform the above test using my TigerVNC binaries, which will confirm whether the problem is specific to my build or not. ------------------------------------------------------------------------------ The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
