Yes, the basics are there in Smalltalk and there's more support built into Erlang. Also: "Live program changes in the Dart VM" https://github.com/dart-lang/sdk/blob/main/docs/Hot-reloa

Not really. Work has been done to make faster Ruby language implementations. https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

If only we could look at the numbers without the uninformative distraction.

Do you really not understand that the exact same Java programs are likely to be 10x slower without JIT? Different language implementation, so different performance. > too seriously Take those measurements just seriously enough.

Another language comparison repo with hard-to-read presentation. The chart axis labels and bar labels overlap each other, and there are no vertical grid lines. Oh for a simple HTML table!

I imagine we need a nuts and bolts definition of "virtual machine" before we can make a comparison.

by igouy 2y ago
Perhaps you mean that "the methodology" does not include an explicit step intended to amortize runtime startup. Perhaps the tiny tiny programs none-the-less took enough time that startup was amortized.

Does JavaME have a "huge virtual machine" ? https://www.oracle.com/java/technologies/javameoverview.html Do you mean CPython or PyPy or MicroPython or ?

The question is: How much slower? We could try to count how many times the java circle crosses left-to-right and right-to-left, in the time it takes for the PHP circle to cross left-to-right once. That's error prone but should be appro

We can read the relative difference from the length of the bars because the bars are stable.

Maybe that dozen lines of code isn't sufficient to characterize performance differences? Nearly 25 years ago, nested loops and fibs. https://web.archive.org/web/20010424150558/http://www.bagley...

Cover up the single column of lang/secs and then try to read how big the difference is between java and php from the moving circles. You would have no problem doing that with a [ typo histogram should say bar chart].
