If you find the indexer too slow, then feel free to tweak it as you wish: /home/user/.config/tracker/tracker.cfg 1) scrolling effect is nothing more then a bunch of integer calculations on screen. how a floating point unit (FPU aka. "hardware accelerator") can help on this exactly? 2) 16 bit sampled music formats (such like mp3, flac, ogg, etc. (only a few studio materials/studio work relays on 32bit floating-point sampling)) are again full of integers. how an FPU unit can accelerate on this, again? 3) do you know that in any phone, the FPU aka. "hardware graphics accelerator" runs 99% of it's time on 'idle' while drains energy 100% of the time? This is amazing. A chip, witch does nothing just drains energy and almost has no use. By the way, did you ever considered tweaking your transitions.ini ? If symfonie is too laggy for you then: 1) turn of the software equalizer 2) organize your musics into folders and sub-folders otherwise you take no advantage of symfonie. (i did not used the newer versions, so i hope these hints will help)
