4 threads for compression give a quite good compression speed vs CPU usage ratio.
Most servers nowadays have e.g. 40 or more CPU threads. Spawning that many threads by default is not great for performance.

Totally reasonable! I'll make a release later today / tomorrow morning.

Thank you for the feedback!
