embryo speedups...
this makes embryo just about the fastest "scripting vm" around - unless you
tie yourself to a particular cpu and add a jit for that cpu (which embryo
doesnt have).
bash: 4681.700 (estimate - ran only 1/100th of loop)
python: 38.193
ruby: 21.015
perl: 18.925
java (gij-3.4) (no jit): 2.484
embryo: 1.041
java (kaffe) (jit): 0.176
c: 0.157
notice emrbyo is more than double the speed of the java vm. this is all
portable code - no jit tied to 1 cpu. we can add that later per cpu - but for
a vm/scripting solution thats cross-platform and runs anwyeher on 32, 64bit
cpus, ppc, x86, x86-64, alpha, arm, sparc, mips etc. it's pretty damn good.
yes this test is VERY naieve and simple and only tests a subset - but it
tests the general execution and interpreting engine, being able to make
logical decisions, interpret code and do math operations. we should do a more
comprehensive test, but this is pretty good for a simple one.
here's the source used:
bash:
#!/bin/bash
I=1
while [ $I -lt 1000000 ]; do
let I++
done
python:
i = 1
while i < 100000000:
i = i + 1
ruby:
1.upto(100000000) { }
perl:
#!/usr/bin/perl
for ($i = 1; $i < 100000000; $i++) {
}
java:
public class loop {
public static void main(String[] args) {
int i;
for (i = 1; i < 100000000; i++) { }
}
}
embryo:
main() {
new i;
for (i = 1; i < 100000000; i++) { }
}
c:
main() {
int i;
for (i = 1; i < 100000000; i++);
}
