	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).

Except when they don't.

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

> Huh.

The hardware changed.

The way measurements were made changed.

The Java version changed.

The SBCL version changed.

> side by side

You'd have to say what you mean by that.

They appear, literally, side by side, in the list. That is, they were competitive eight years ago. They are still competitive today.

By design, the 8 year old page you linked presented Lisp measurements side-by-side against Java measurements (by excluding the other programs).

There's overlap across most of the different language implementations:
