zRam for building
« on: May 12, 2017, 09:06:24 PM »
Came across this.
http://geektillithertz.com/wordpress/index.php/2017/03/16/raspberry-pi-zram/

We all know Pi3's only have 1GB, compiling big stuff takes a long time as stuff is swapped to SDcard.
Bela talks of overnight type build times :o

Since I am very new to using piCore for compiling I want to know if this is already part of  piCore?
I have seen the zram0 stuff on boot but never really paid attention to it.

Is anyone else doing long build time stuff with piCore?

Zram is enabled by default.  But the size of the ram disk is predetermined during the boot cycle.  The size is a percentage of the total memory.   I forget the actual percentage, but if you look at /etc/init.d/tc-config, you will see it.

If you want to play with increasing the size.....add "nozswap" to the command line, then you can setup by yourself in bootlocal.sh
