Well, sure if you want to use 1000 servers instead of 100, go ahead and use it. No wonder Facebook noticed this and desperately trying to compile Php to C. Perhaps if Blekko ever gets popular we will see if their choice will bite them. Also an anecdotal example. Two months ago a friend of mine wrote a rather complex algorithm in Perl (He is very fluent with it). It was a novel sentence alignment algorithm using Gibbs sampling. Algorithm was hard to make parallel and not cache friendly. He needed to wait more than a day for training the system in a server. Well, long story short, with his help another developer converted it to Java in short time it worked around 200 times faster. So there. Moving bits around did not help Perl here at all.

>>Blekko ever gets popular we will see if their choice will bite them. What choice? The only reason why Blekko or Facebook is even able to launch and turn around things quickly to survive in competition is because they opt to use dynamic languages like Php and Perl. If they started doing their projects in C, with the current growth in rate of complexity they will never finish their projects ever. >>No wonder Facebook noticed this and desperately trying to compile Php to C. Dynamic languages aren't slower because they are not C. They are slow because they do a lot of magic. C is fast because the magic is left for you to perform. I can't see how any one pull out pace out of compiling Php to C directly, unless they sacrifice things along the way. Which really defeats the purpose of using Php at the first place. >>Well, long story short, with his help another developer converted it to Java in short time it worked around 200 times faster. So there. Moving bits around did not help Perl here at all. Number of programmers who even need to here the word 'bits' in their day to day activities(Talking of application programmers) are rare enough to make their case totally exceptional. Besides there are places where C makes perfect sense. There is hardly any other language heard of in the embedded programming world.
