[I am forwarding this to the mailing list on Soorya Kuloor's behalf]
We are using cairo on a real-time schematic display application. We have
run into some serious problems during redraws. The schematic displays
have animated parts that flash with alternating colors when there are
problems with the monitored system. When the flashing happens cairo
consumes more CPU cycles than is acceptable. We think the only choice
for us is to speed up Cairo. We need speed up of atleast by a factor of
2 and we have until Monday to do this :-((.
We are using cairo version 0.1.17. We are using the pixman backend and
we cannot use Render backend. Would there be any benefits to moving to a
newer version? May be the OpenGL backend? Is there any particular part
of Cairo or the libpixman, that we can speed up? We do not use any
sophisticated capabilities such as transparency or pattern based fills.
We use text (a lot).
Any suggestions or help is greatly appreciated.
