Just to add some more comment on MAX_FLUSH_VERTICES - when set to valu 96 - it gives the highest throughput on x11perf -aa10text 3.7MChar/s - using any higher value doesn't make any different (so the max seems to be somewhere between <64-96]
Also when this 3.7MChar is rendered - the parallel move of some other window on the screen becomes very slow - so engine gets overloaded ??
Or the Xserver generates such long queue of events it becomes so slow ?
