Ok. Now the confusion is resolved. 1) Speed improvements of 70% and up that I reported yesterday are really exist. I just reproduced a 3.47 times model speedup and 2.15 overall speedup for my app (r875 vs r822+inits). BUT this app is atypical. I have added some time measuring code there so it prints out two lines per each model init. So when I am testing perfomance - screen very quickly scrolls up
2) Simply commenting out two print statements gives me only 1.67 overall speedup given equal other conditions. I think that processor receive additional interrupts from videocard that in turn results in more often checks of tasks queue. 3) I declare all my previous testing results spoiled by noise generated by print statement and inappropriate kernel scheduler setting. I've set up yet another test box with these parameters: Intel Core2 Duo 2.66GHz, 2G RAM, Ubuntu 9.04, 'server' flavour kernel 2.6.28-11.42. Initially I considered to install a 'realtime' kernel, but it appeared to be unstable on that hardware (and afterall - it's for sound/video processing and 'server' type is more likely to be installed on servers). Will report new testing results (and finally I hope to write 'optimised inits ver.2' patch) later today.
