Public bug reported:

Binary package hint: xorg

Hi,

I am the owner of a Samsung NC20 netbook with a Via Nano CPU and a Via
VX800 chipset. With karmic I was able to play most fullscreen flash
videos fluently. After the upgrade to lucid, this it no more possible. I
already found and fixed a bug for me (Launchpad Bug #574733) and the
performance got measurably better, but there is still a major regressen
and fullscreen flash is like a dia show.

I think I got a way to show/measure the problem with x11perf -shmputxy10
-shmputxy100 -shmputxy500:

1: x11perf_exa_karmic.log
2: x11perf_xaa_karmic.log
3: x11perf_exa_lucid_patched.log
4: x11perf_xaa_lucid_patched.log

    1              2                   3                   4           Operation
--------   -----------------   -----------------   -----------------   -----------------
152000.0   109000.0 (  0.72)   159000.0 (  1.05)   121000.0 (  0.80)   ShmPutImage 10x10 square 
 22300.0     1890.0 ( 0.085)    22900.0 (  1.03)     1940.0 ( 0.087)   ShmPutImage 100x100 square 
  1020.0       76.0 ( 0.075)     1020.0 (  1.00)       76.7 ( 0.075)   ShmPutImage 500x500 square 
157000.0   108000.0 (  0.69)    18600.0 (  0.12)    19800.0 (  0.13)   ShmPutImage XY 10x10 square 
 22200.0     1920.0 ( 0.086)      324.0 ( 0.015)      278.0 ( 0.013)   ShmPutImage XY 100x100 square 
   996.0       76.0 ( 0.076)       11.3 ( 0.011)        9.2 ( 0.009)   ShmPutImage XY 500x500 square 

As you can see, EXA is better than XAA, but more important, lucid is
much worse than karmic for the ShmPutImage XY test. As these numbers
relate very good to my fullscreen flash experience, I think this may be
related.

Kind regards,
  Thomas
