Thanks! I will merge the PR once tests pass.

Apparently the more expensive EC2 instance is indeed running faster 😉

EDIT: You do have .pyc files. I suppose your machine is just slower than my VM…

Running on an 2015 macbook at the moment and an underpowered t2.medium instance, both are about 6 seconds off of master. Just tested an m5.2xlarge and that’s about 3.5 seconds off of master.
