random thought: preparing things like e.g. test execution for remoting via snapshots and not direct execution in the working copy seems like it might present opportunities for highly parallel local execution in addition to remoting for e.g. offline perf. fwict, few tests actually ever peg modern CPUs for long periods of time. concurrent parallel execution around snapshot copies could allow us to oversubscribe processes/threads/“actors”/etc at the OS level that could saturate CPU/IO/etc for faster end to end execution, assuming the overhead of parallel setup isn’t too costly.
