@Andriy Knysh (Cloud Posse) I have ~5 PRs incoming to tackle the recent flakiness. It's partly due to the harden-runners, but also other things like windows defender scanning every file we unpack from the cache. Turning that off for cache unpacking reduces time from 5-10m to ~1m.
Here's the first PR in the series.
