Tuning Sonic Pi for best performance
Several of the programs I write for Sonic Pi push it fairly close to the limit when run on a Raspberry Pi. This note gives some tips on to how to maximise the performance on that platform. Of course, if you run Sonic Pi on Mac OSX,or a Windows PC then the performance is much better on these more powerful platforms and some of the issues may not arise.
Over-clocking your Pi
By increasing the voltage applied to the Pi processor, and running it at a higher clock frequency than normal it is possible to achive significant gains in performance. The down side is that you may reduce the lifetime of your Pi. There are five levels that can be configured: None, Modest, Medium, High and Turbo. I routinely run my Raspberry Pis with Medium Overclocking and have noticed no ill effects on any of them.
If you wish to apply some over-clocking you do so by running the program raspi-config from the command line. Having logged on, from the command line before you start the gra
