11/13/2019, 9:16 PMto this end: I have heard lots of complaints of late about multi-second pex execution startup times from Twitter folks, I worry it’s gotten worse recently. that’d be a core problem to fix in both pex and any carry-forward.

11/13/2019, 9:32 PMwe should take care not to affect use cases that don’t need that reproducibility though

11/13/2019, 10:30 PMprobably something that needs to be benchmarked and profiled for optimization
