[CinCV TNG] Benchmarking different versions of Cinelerra?

Hi, all!

I tried to compare playback performance between three different versions of 
Cinelerra, but as Einar correctly warned - benchmarking is not simple! While 
for my system some parameters like visible track size (32->64->128), and 
resolution of timeline doesn't play such big difference - on other systems they 
may slow down things more or less, compared to decoding/effect 

So, may be standartized set of Cinelerra (CV | CVE | GG) config files can be 
developed, along with publically-accesible test videos in various formats?

Right now I was quite surprized to realize CinelerraCV (according to numbers it 
displays in preferences window - big red fps number) can play 1280x720 25 fps 
yuv420 mjpeg AVI file at 16 fps, while CVE only does 10, and GG just 8 at 
most ...may be those calculations are not prescie enough, and different codecs 
will show different behaviour/performance, I think. Also, I understand often it 
simply too early to optimize not yet debugged code. 

Also, I was wrong in my observation only CVE was not utilizing all four cores to 
100% during playback-only - they all mostly load cores to 80-90% - so hopefully 
there is some room for improvements.
