API Calls & Framework... IDK

Inexperienced programmer (just started a week ago, no shit I'm just now understanding why classes rock so hard.). If making API calls to linked libraries in statically compiled binaries is faster than using a framework that uses JiT compilation... why do so many people push for the framework and JiT compilation?

I'm not trying to start anything, but I'm seriously curious as to why the later is the preferred choice.

Like a bunch of thing popped into my head and shit. Break from reading. And I got more questions:

1) Where can someone get lisp? (I tried to find it on google and it said I had to compile the programming language I want to use.

2) Why the fuck do they teach C in school if there's a language this easy?

3) If I have to compile it myself then what do I use to compile it cause idk what language this is in.

- The teacher spent the first 2 days going over compiler options. Something about how the binary is compiled is almost as important as the code.

- The original question came from referencing "benchmarks tests" in the school book. And seeing chart after chart on google (both everything & images)

side note:

Yes, I know I'm a bit over the place but my brainz a buzzin.
