Interestingly the RPI B+ runs at a steady 0.3% load while streaming 24/44.1 to USB. The Cubitruck runs currently at around 0.7%.
That surprised me, considering 3 times higher overall performance of the CT. Some ideas. 1. I do think that due to the low specs of the RPI people try to make it's firmware/drivers etc as efficient as possible. The SW is well maintained. 2. Multiprocessor systems need a well structured setup to perform highly efficient. The base setup for the CT no matter if we talk ArchLinux or Debian doesn't really focus on high efficiency in a MultiProcessor environment. The 2nd CPU sits idle 99.9% of the time by default. I doubt that the situation is much better on other 4-core boards. On pretty much all other platforms, beside RPI, nobody really bothers to squeeze most out of the respective platform. First there are usually plenty of horsepowers available. As you can see some posts back, people give a damn if a (or two or four) CPU(s) run(s) at 35% or 0.35% for doing the same job. And 2nd 6 months after launch most of these boards will be replaced by a new product anyhow. It's just not worth to spent a lot of time on improving such a product (drivers and firmware). Usually you're really lucky if the biggest bugs get fixed during that time frame. All that is different if you look at the RPI situation. However. The RPI remains a single purpose machine for me - "ethernet-in/usb-out". Server and DSP duties are not the RPIs strongest characteristics. My multichannel setup still runs on a CubiTruck. Beside that I use a high quality PS for the RPI B+ and applied some little onboard HW modifications. Basically it is the SW AND my SW configuration AND the modified HW, which brought the RPI back into the game. Cheers PS: I never really liked PicorePlayer. ::: ' Touch Toolbox and more' (http://soundcheck-audio.blogspot.com) ::: by soundcheck ------------------------------------------------------------------------ soundcheck's Profile: http://forums.slimdevices.com/member.php?userid=34383 View this thread: http://forums.slimdevices.com/showthread.php?t=101624 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
