building up a 3x3 mosaic I found, that the cpu usage does not increase linear by adding channels to the mosaic. I get the following values of cpu usage
playing 1 channel 1%
playing 4 channels 2%
playing 5 channels 12%
playing 6 channels 21%
playing 7 channels 58%
playing 8 channels 88%
playing 9 channels 99%
all channels have the same configuration, OS is Win XP Pentium 4 2,8
