Xomap 3x more fast
During these days I found this patch[1] from Dan Amelang about a Xorg optimization to work with pixbuf composite (888 over 565). This patch makes Xorg about 3x faster. I made a little change in the patch for optimization of another function too.
I've exchanged some e-mails with Dan, and apparently this patch has a problem with small images but I didn't find this problem yet. If someone would like to try this patch you can install the package[2] above and if you get the bug, please report to me. But be careful because this patch is an experimental code and can freeze your X server.
You can verify the performance with this example code[3].

Incompatible application package.
You need install this using dpkg -i http://www.renatofilho.com/files/xserver-xomap_1.1.99.3-0osso37_armel.deb , this is incompatible with package manger
Do you know if this also applies to the Nokia 770? Do you have the source package online somewhere?
Thanks!
the source you can get using apt-get source xserver-xomap inside of scrachbox, and apply this patch http://www.renatofilho.com/files/fbpict.patch
I installed it.. don't really notice a difference, honestly.
this patch only speed up, operations with pixbuf, you can test this with composite example application.
Should this make scrolling in the browser smoother? I think it does, but I could be fooling myself.
Attempting to select text in the browser locks my device every time with both opera and microb. I have to remove the battery to recover.
The browser doesn't use pixbuf =)
and daniel stone who maintain the x for the maemo already received this patch since april, so it should be already on chinook.
No, Dan talked to me, and the patch has not been applied yet because of probable bug with small images.
