[root@f29h ~]# cat /proc/sys/vm/swappiness
This is now widely regarded as sabotage, because it's simply too
aggressive for the amount of RAM we have these days compared to 4MB of
RAM. Upstream is unlikely to change it, they've been beaten over the
head for years about it.
# echo 1 > /proc/sys/vm/swappiness
I've seen suggestions to use 0 as well.
Now do whatever normally blows things up, and report back. I'm
curious. If the problem is simply too aggressive swapping, then
neither zram nor zswap will make that much of a difference (it will
moderate the transition to depending on swap, but once it's
pathological, you'll still be screwed if this is really just a
workload for which swappiness 60 is flat out bad).
I'll try it when I can.
How do we change this default for Workstation? Is it a kernel tunable?
