Can Squeak be faster than Java? Yes :-)

Code in Java:
int a = 1;
int b = 0;
long startTime = System.currentTimeMillis();
for (int i=0; i<1000; i++)
{
try {
try {
int c = a / b;
} catch (Exception e1) {
try {
try {
int c = a / b;
} catch (Exception e2) { int c = a / b; }
} catch (Exception e3) { }
}
} catch (Exception e4) { }
}
System.out.println(System.currentTimeMillis()-startTime);
Code in Smalltalk:
| a b c |
a := 1.
b := 0.
[
1000 timesRepeat: [
[
[
c := a // b.
] on: Exception do: [
[
[
c := a // b.
] on: Exception do: [ c := a // b ]
] on: Exception do: []
]
] on: Exception do: []
]
] timeToRun
On my notebook:
Java: about 36 ms,
Squeak: about 25 ms
VisualWorks: about 12 ms
C# (on the other machine): more than 100 ms
