System optimizations?

[barryso]

A couple of observations.  Take them for what they are worth.

I added the CRAAP settings to /boot/config.txt and then listened for a bit.  Then added 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


There are definitely sonic changes that happen with these updated settings.  It sounds like the imaging is a bit better and there was a bit of midrange to high frequency grunge that went away.  Things seem more three dimensional.

It'll take a while to listen and decide if these changes are better or just different but it's worth trying if you feel comfortable editing Linux config files.  Just copy off the original files so you can go back to the original settings if this isn't to your liking.

Nice tweaks.

Thanks.
