I question your use of the word "quick" to describe this though :laughing:

Ah yeah, there are some CLI flags to control how many processes and iterations per process to use, which can help lighten the load.

Also there are some known deficiencies in the crate we use to get cycles that makes this a LOOOOOT worse than it should be.

But thanks for taking the time!
