alt Hacker NewsSo 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.

Insane. Does it possible to fork to another bare metal machine? Maybe multi region as fly io. If not, I bet you have huge disk sizes on your machines to store all the snapshots (you said, you store them and bill only for disk space).

O(1) What! What might bring it down to say 10's of ms? Looks like its some kind of optimizable wall that its 500 for everything.
Like with 10ms then online replication/backup — analogus to litestream for sqlite — but for in memory processes becomes feasible, no?
