I don't think FastCli is actually faster than Cli. Just marketing hype.

FastCli has that always-running agent, which is a game changer!

I vaguely recall something about M5 and engrams, but I can't remember how that relates to speed.

I thought FastCli was just a marketing gimmick, so maybe option B is correct?

I'm not entirely sure, but I feel like I saw a question about programming languages in a practice exam, and C++ is usually faster than Perl.

I think I remember that FastCli has some sort of agent that runs continuously, so maybe that's why it's faster?
