Thanks for your comments, in the context of measuring the server-side FaaS execution thankfully SecondState’s SSVM will cold start in less than 20 milliseconds.

All functions undergo AOT optimisations when they launched.

I guess from the broader round-trip, the other factors like new client — server connections, page loads and so forth are another area to potentially optimise, yes.

The great thing also is that the broader FaaS system as a whole provides additional functionality for the web i.e. callbacks, webhooks etc.

Here is a link to a really interesting paper regarding performance analysis of Wasm VM

Thanks again for your comments
