It would be great if the picture demo running the node application included timestamps. The landing page keeps using "fast" to mean "bandwidth" but without any mention of latency - my primary question is how long it takes to boot the kernel and start launching the userland process (i.e. cold start time) but there's no mention of that.

We've seen boot times in the 60s and 70s of ms but have put absolutely no work into optimizing that. We could drive that down substantially for payloads like virtual network functions.

I should point out that boot time is highly dependent on two things: infrastructure of choice and application payload. For instance, your typical rails or JVM payload might take longer to init then actual boot time. Similarly booting on Azure can be different than booting under firecracker on your own hardware.
