I'm also using zstd for lots of stuff. It's really performing very well.

But it often behaves totally unpredictably. For example, I get a better 
compression ratio with SQL files in level 1 than with level 3. And level 
6 is significantly slower than level 4 with the same compression ratio.

But overall performance is always better than its competitors.
