Yes.

However, "fast enough" can have a cost. Take a hosting service running a
thousands of sites on a Linux box. If many of those sites run PHP shopping
carts, forums, content management systems etc, the server will have less
capacity. This means buying and managing more servers - its a real cost.

Agreed.

Everything is a tradeoff. :)

The beauty of PHP is that its like the old BASICs of twenty years ago. You
can't crash it. Its cross platform. The script IS the "executable" - No
compilation needed. When I upload a PHP script, I don't worry about binary
compatibility, linking to libraries, or getting into trouble with the
hosting company. If my script goes off the rails, PHP talks to me, or I can
put in some debugging strings. I can run it on my desktop for testing. Its
such a low effort enterprise. I don't like the PHP language, but its got
everything laid on, and I hack away happily when I need to.

I agree.

The Roadsend PHP compiler is interesting - you can debug your script as
interpreted, then compile it to native code. Except the benchmarks only
show 2x speed increase, so I think the PHP system is itself slow - all those
untyped variables.

I'm not sure why PHP is "slow", but if someone needs more throughput
there are ways to make things faster through caching and things like
that. But caching is a tradeoff too :)
