I wonder whether the Intel driver can get at least close to Nvidia driver. I ran x11perf on Nvidia system and Xserver *without* the glyph cache. Compared to these numbers, the Intel driver seems to be a bit comic with 56k glyphs/sec with EXA or 215k glyphs/sec with UXA. x11perf -aa10text Sync time adjustment is 0.0603 msecs. 40000000 reps @ 0.0001 msec (6990000.0/sec): Char in 80-char aa line (Charter 10) 40000000 reps @ 0.0001 msec (7000000.0/sec): Char in 80-char aa line (Charter 10) 40000000 reps @ 0.0001 msec (6940000.0/sec): Char in 80-char aa line (Charter 10) 40000000 reps @ 0.0001 msec (7000000.0/sec): Char in 80-char aa line (Charter 10) 40000000 reps @ 0.0001 msec (6990000.0/sec): Char in 80-char aa line (Charter 10) 200000000 trep @ 0.0001 msec (6990000.0/sec): Char in 80-char aa line (Charter 10) -- Lukáš Hejtmánek _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
