System optimizations?

[moodenigo]

The only tweaks I have applied are the following:

- added in /boot/cmdline.txt: isolcpus=2,3
- changed options in /lib/systemd/system/mpd.service
    CPUSchedulingPolicy=fifo
    CPUSchedulingPriority=70
    Nice=-15
    ExecStart=/usr/bin/taskset -c 2,3 /usr/local/bin/mpd --no-daemon $MPDCONF

[color=#000000][color=#000000][color=#000000][color=#000000]I did [size=small]not change anything else. This made some difference!

Hi, Roberto

What difference did you hear?

PS - running userspace processes on isolated cores is probably more like running with a low-latency kernel than a so-called real-time kernel, but it's definitely worthwhile for latency-sensitive tasks.

Differences: subtle, but clear improvement in imaging, and perhaps some clarity (you know, when audiophiles say "like a veil being removed" which means all and nothing). I suppose the better timing did something then. Thanks for the low-latency remark.
