I’ve noticed that the buster image seems to have 100MiB swap enabled on /var/swap. I’m currently testing ZRAM from here https://www.novaspirit.com/2016/12/24/increasing-ram-raspberry-pi/
on my 1GiB pi4 it gives me an effective extra 1GiB ram. I’ve been testing with my usual snapshots and the computational overhead hasn’t had much effect.
Unfortunately it’s still not enough to load the Ivy Audio Piano in 162.
Does anyone know of a SFZ file that linuxsampler struggles to load in 1GiB that might load in 2?
