Triode.
Find enclosed the 300Hz.patch. It's been successfully applied on the
Cubitruck Debian project and Cubitruck Arch image @ Cubieforums. It
applies to 3.4 kernels.
On e.g. kernel 3.16 for RPI, CONFIG_HZ is no longer hardcoded for ARM.
You can change it with menuconfig. I did some benchmarking. You can read
at ARCH-ARM forums - kernel developer section about it. The most obvious
advantage: linpack gave me 6% higher performance for RPI@250Hz then
stock 100Hz. Note: RPI worked better with 250Hz.
CT works well with 300Hz. IMO the whole system runs smoother with lower
latencies.
