Agreed, but my math also says that if this is your pain point, you'd save even more time by not firing off more VMs? That is, skip the startup time entirely by just not doing it that often.
I don't startup VMs multiple times per hour, much less per minute, so I don't assume to know what tradeoffs the people using firecracker are making when deciding how often to startup VMs.
Fair. I still feel fine pushing back on this. The amount of other resources getting wasted to support this sort of workload is kind of easy to imagine.
I will put back the perspective that they were not hunting for 2ms increases. They were originally chopping off at seconds on startup. The progress they made is laudable. And how they found it and acted on it is great.
