PulseAudio performance test (Karmic?)

[onemyndseye]

I ran some tests tonight and stumbled on some interesting results...

First, I noticed my FPS has really suffered lately. So i started looking into it. And I found that turning RO's internal volume control all the way down make a HUGE difference. Not just 10-20fps. But LARGE jumps in FPS.

So I starting thinking ... hrmm.. I wonder if PulseAudio is bottle-necking RO..?

Testing was simple enough: Launch RO and turn in a circle until FPS stabilize and take a screen. Repeat bypassing PulseAudio (of sorts)

Test1 (Normal Launch):

onemyndseye@onemyndsmobile:~/regnum$ ./rolauncher

Result:

Test2 (Launch with OSS):

onemyndseye@onemyndsmobile:~/regnum$ aoss ./rolauncher

Result:


WOW! O.O


These results are in no way conclusive or even 100% consistent (so far I would say 80% consistent) and I will continue to test, but the results were so surprising I wanted to share and get a discussion started on this topic.
