We fixed a kernel bug that would have caused unreliable results for the kind of things that glean is doing. Reliable results meant slower behavior.

Haien says it > takes about 9~10 hours. > hi, the result I told you was tested two weeks ago and the case seemed like paused in the begining of testing. I retest texCombine last night with the latest build, and it becomes rapid. now it takes 4 hours without option "--quick", and 3 minutes with "--quick". With the newest code, both blendFunc and texCombine passed quickly. Only readpixPerf still runs several hours(it can't finish in 4 hours).

The performance with --quick appears to be acceptable. (In reply to comment #7) > At this point --quick is required for quick testing, due to exposing more > visuals. The performance with --quick appears to be acceptable. On 945GM, it only takes 2 minutes with --quick option and it without --quick option it will take 2 hours now with the newest code.
