to other processes to be swapped back in. So, for example, immediately
after closing a web browser that was using gobs and gobs of memory, you
might see that the "used" memory drops dramatically, and "free" m

The rule of thumb to which I am accustomed is to have a swap space
double the physical RAM. If necessary, you can create a swap file a
Hi all,
I run a tiny and lightweight Debian 9.9 LXC container on Proxmox 6.2-6.

50-100 MB to operate.
Last year I started seeing about half of swap being used with very
little use of RAM.
I then made the following
swapping, which indeed is not ideal..
I am modifying my code to batch this procedure to lower the gargantuan
memory requirements of my image registration task, but in the meantime, for
processes with large memory requirements that may occasionally need to
swap, I found this kernel tuning at least

Dear all,
TL;DR/summary:
- Tuning vm.watermark_boost_factor to 0 (disable) on Debian
significantly improves performance on memory-intensive tasks that utilise
SWAP space, by stopping preemptive kswapd freeing of memory, and
subsequent page thrashing.
- I suggest that Debian should
