I had a test with ElfData.
The closest I can get to the perl version, is taking 72 seconds for
ElfData, but 52 seconds for perl.
I'm assuming my Mac is slower than Kem's ;) It's an old iMac G5.
I'm not going to publish the ElfData version yet, as it's a bit
under powered. I had hoped to beat perl, but obviously not. Still,
the ratio is better, I am at least around 3x faster than the ratio
Kem reported, even if not faster than perl.
I would suggest, that perl has some really amazingly well optimised
string functions or just a very good optimiser. I'm not sure what
is taking ElfData longer than perl, but I'd like to know!
Simple enough -- <http://www.perl.com/download.csp#sourcecode>. As
for this example, I'd be looking at I/O and the execution speed of
the loops. Studying the object code might be interesting.
