using zram?

I've got an ancient Acer Aspire LC-3003 that only has 700MiB RAM, and uses the Bunsenlabs Helium 32bit non-pae kernel. In the past I've got noticeable performance improvements by using zram. On Ubuntu systems, I do this by running: sudo apt install zram-config.

How do I setup zram in Bunsenlabs Helium?

Re: using zram?

I don't see it is available for stretch/Helium, but on testing this is what I see...

 apt-cache search zram
libblockdev-kbd2 - kernel block device plugin for libblockdev
udisks2-zram - zram support for udisks2
zram-tools - utilities for working with zram

 apt-cache show zram-tools
Package: zram-tools
Version: 0.3.2.1-1
Installed-Size: 28
Maintainer: Jonathan Carter <jcc@debian.org>
Architecture: all
Depends: bc
Description-en: utilities for working with zram
 zram is a Linux kernel module that allows you to set up compressed
 filesystems in RAM.
 .
 zram-tools uses this module to set up compressed swap space.
 This is useful on systems with low memory or servers
 running a large amount of services with data that's easily swappable
 but that you may wish to swap back fast without sacrificing disk
 bandwidth.
 .
 By default it allocates 100MB of RAM, you can configure this in
 /etc/default/zramswap.

Safer to use it the Debian way though....

Re: using zram?

Thanks for your ideas. I really don't want to use testing...
I'm going to monitor it for a few days and see what happens. I must admit that using zram on a machine where the bottleneck appears to be the CPU doesn't make a lot of sense to me. But I like to experiment. I can always reinstall if I break it!

Re: using zram?

I have zram in substitution of swap to avoid writings in ssd, in addition it is faster followed this post.
