Have you looked into whether the advantage of your DB stems primarily from more efficient I/O batching or from faster command execution after?

And its especially interesting to know whether performance profiling was used for optimization and if so do any flamegraphs still exist?

Wow) I like the idea of making __map a builtin instead of forcing users to simulate recursion through macro expansion. One thing Im curious about is how you handle expansion semantics. Consider: #define X 42 #define STR(x) #x

__map(STR, X)

Should this produce "X" (like STR(X) does), or "42" (if __map expands its arguments first)?
