Yes exactly, this is vm.swappiness.
Here is the value :
$ cat /proc/sys/vm/swappiness
0
I tried with a swappiness of 1 and 10 but the behavior is similar. The
swap is permanently used while the RAM is not full.

Since we migrated Debian Jessie to Buster, we realized that

We have 0 swappiness to force the system to use all the RAM before
switching to SWAP.
Unfortunately, this setting doesn't work anymore and the problem
is that our whole platform has SWAP issues, which slows down its
performance dramatically.
I'm attaching an example that shows on a graph the evolution of
RAM and SWAP usage.
Hi,
Are you saying the setting (you don't specify what setting) is no
longer being set by procps or that the kernel no longer seems to
behave correctly? I'm trying to understand why this is a procps bug.
If you run the command (assuming this is what you are setting)
cat /proc/sys/vm/swappiness
does the value you set appear there?
