How fast would an old-fashioned CGI program (with no FCGI-style pre-started processes) be on modern hardware? Has anyone tried recently?

Serverless a la Apache OpenWhisk is CGI more or less, with reuse and concurrency optimizations and an entire flexible function/script deployment model on top.

Basically everything is more or less like CGI. I鈥檓 just idly wondering whether all the optimizations are still justified vs a simple process-based solution

There is also the startup time of the code itself, which benefits if it鈥檚 not a full code start. Even if you already optimize it. Notably for interpreted script languages of course. That still matters when you care abou <100ms or so.
