Improve training cascade speed

Hello. I compilied Open CV with TBB (at wiki some errors about using sources of TBB (you must use binary files and import folder, also add path of TBB to windows path)). I think that I could use all cores for loading negatives, but only one core used for that....So I have 2 questions: 1) How improve training cascade speed? Now I use this: opencv_traincascade.exe -data haarcascade -vec samples.vec -bg BadN.dat -numStages 16 -minhitrate 0.999 -maxFalseAlarmRate 0.4 -numPos 67 -numNeg 570 -w 40 -h 20 -mode ALL -precalcValBufSize 2048 -precalcIdxBufSize 2048 My image is static (It is logo), for example - logo of HP. 2) How use all cores of server for loading negatives? (I have xeon server for that)

Thanks!
