Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I want to change my zRAM compression algorithm to zstd on openSUSE Tumbleweed
As a bonus, the systemd-zram-service's scripts will create zRAM devices based on the number of your CPU cores. This is problematic as it's a deprecated practice, and can also cause an issue on some multicore CPUs. Basically, we already have "multi stream functionality" since kernel 3.15. And since kernel 4.7, regardless of the value passed to [max_comp_streams], zRAM will always allocate multiple compression streams - one per online CPU - thus allowing several concurrent compression operations.

What happens when there is no more swap partition is full and RAM is full? Does Linux swaps anyway in some other way (maybe swap files like Windows), or can't it swap anymore?
Historically, Linux has created an additional (fixed-size) swap partition or file. In case you mention you get OOM. But for some time there is a great project systemd-swap creating hybrid swap space. You can even find it in the official Arch Linux Community repo.

PERSONAL OPINION: /Swapfile or Swap Partition?
There is also systemd/zram-generator that allows you to create and manage swap devices more easily. And Nefelim4ag/systemd-swap (abandoned?) that automatically creates swap files and resizes them based on RAM usage.

A warning about 5.12-rc1
That sound like what systemd-swap does. Apparently, hibernation is not quite working yet, though.

Can I mix zram with swapfc?
Disclaimer: I couldn't find anything relating to SwapFC other than from the README of systemd-swap. What I've written above is just based on the one-line description of SwapFC, as well as prior knowledge of zswap and zram (obtained from the Linux Kernel docs).
