Why nobody came out write up three pieces of code, one in Perl, one on c, one in Java and show him how wrong he is? Why?

Because:

• You don't feed the trolls.
• Small benchmarks are pointless, unless you have to deal with a specific micro-optimisation (which is rare).
• You don't feed the trolls.
• Raw speed is not the only way you judge the utility of a language. The vast majority of the time it's not that important. Issues of maintainability, development speed, reliability, robustness, etc. are usually more important.
• You don't feed the trolls :-)

(Personally, I disagree with your other comment on an individual monk - but PM is certainly not the place to raise these issues.)

People - please remember the first, third and fifth point above (and note how well points two and four were addressed :-)
