Hello,
My testing has shown that when moving to Unbuntu Focal with graviton2 in https://github.com/MirahezeBots/MirahezeBots/pull/334 was taking longer than Xenial.
I have added pip cache which seems to have sped it up quite a bit but I wondered if I was missing anything else or could change it further.
Feel free to either suggest here or directly open PRs.
Thanks!
