Luajit and SBCL are very much performance competitive with the JVM? Why do you say that they're not?

Random example benchmark: https://madnight.github.io/benchmarksgame/lisp.html

That's someone's 8 year old mirror of the benchmarks game website.

These mean nothing. The C/C++ implementations use SIMD intrinsic while Lisp doesn't (it should have used sb-simd).

Huh. And after eight years, SBCL and Java are side by side, still.
