 Description   

According to https://github.com/facebook/zstd 

"zstd 1.4.5 --fast=7 is much faster than snappy at same compression level.  But right now, there is no way to tell mongodb to use zstd at --fast=7"

Noooo!!!

Without --fast, Zstd is not as good as Snappy. With --fast it immediately becomes a no-brainer.

Surely this is doable? I understand --fast is just a negative compression number, why not just allow negative numbers in the command line switch?

We updated the fix version - but there is no change to the priority of this work - we still have this high on our priority list.
