the problem is, the glxgears portion of this test is an _inverse_ testcase. The reason? glxgears on true 3D hardware will _not_ use X, it will directly use the 3D driver of the kernel. So by renicing X to -19 you give the xterms more chance to show stuff - the performance of the glxgears will 'degrade' - but that is what you asked for: glxgears is 'just another CPU hog' that competes with X, it's not a "true" X client. if you are after glxgears performance in this test then you'll get the best performance out of this by renicing X to +19 or even SCHED_BATCH.
