alt Hacker NewsCongrats guys! Would share some technical details, I bet you have great stories to tell. Let’s, what is forking? You completely copy disk, make ram snapshot and run it? If CoW, but ram? You mentioned 8GB ram vms. Sounds like impossible to copy 8Gb under 500ms, also disk?
So fork time is actually O(1) with VM size, its 500ms even for 64gb + disk. We're using some pretty weird COW techniques to pull it off.
