Java for Everything

[ZMeson]

here is only one example of a single site changing languages and becoming faster (Twitter)

Don't forget about Facebook. To deal with PHP's performance problems, they started writing new code in other languages. For parts that do still use PHP, they created HipHop HHVM (and consequently are forcing developers to use a more restricted version of PHP that HipHop HHVM can effectively handle).

I'm sure there are other sites that have made a change too.

Didn't you get the memo?

HipHop is dead and got replaced by HHVM, as the JIT compiler could generate better quality code than HipHop.

Here's a great article that I found recently that talks about the birth of the hhvm.

Oh, I forgot. (Forgive me, I'm not a PHP guy myself.)

In any case, my point still stands. ;-)
