Debian 10 PREEMPT_RT Kernel Benchmarks
« on: February 15, 2021, 10:18:26 pm »

FWIW, here is a realtime benchmark.

This is a cyclictest benchmark of MC26 running on Debian Buster with backports PREEMPT_RT kernel 5.9 playing 192kHz content through 6 channels of convolution FIR filters containing 256K taps, steep 384dB/octave XOs per channel.

Hardware is an old Gigabyte PCIe 2 Mobo with an Ivy-Bridge i7-3770K CPU, 16GB of DDR3 memory, early gen SATA SSD and onboard graphics.

Max system latencies are 21 microseconds.
