It looks like you have some options but I haven't tried any yet, so I can't
help you with the installation

Dear Kevin, please install and use the PECL bcompiler extension. You will
need to use the approprate version for your php

Checkout HipHop by the Facebook guys, it turns PHP into C code and compiles
down to binary.
...although I don't think it's for the faint hearted.
Have you tried other optimisation techniques first - eg Caching, and
Profiling?? If this is a production environment you might wanna think about
increasing resources or introducing a load balancer (in the case of PHP based
websites)

PHP gets compiled to bytecode on the server before being executed.
You can cache the precompiled code with (for example) APC.
Unless your code is several thousand lines of code (or your server very
slow... 486-slow), the compilation phase is not that long.
I think your main problem can be one of:
1- wrong algorithm
2- long waits (database, files, network, etc.)
3- heavy calculations
Solutions:
1- find and use a different algorithm
2- Try to parallelize code (with gearman or similar, or via pctnl_fork)
3- rewrite the heavy functions in C, C++ or Go and compile them, then
call them via PHP extensions or via gearman/fork.
Bye.

If you are putting them up as examples, then it would be good if there were
plentiful comments that said what they were supposed to do, why, how ...

The usage of the examples:
1. the name of the php file reflects to the method(s) under consideration ->
find the related php.net manual page for more information
2. scroll down in the file, and you will find the result of the execution

Why don't you post them on php.net?

Thanks, I have heard about that feature for the first time. I will examine it.

Another thing you can do is store both page "renders" as well as database
results in http://memcached.org/ blobs and pull from those in intelligent ways
(you can creatively mix and match "live" stuff with cached stuff and you can
make pages expire in defined hours via your cache class or even a crontab).
We also add another layer in that if a blob exists in the memecached but not
locally, we save it locally for the next hit. Depending on your hardware though
the Gigabit/Fiber might be faster access than a local HD/SSD/RAM disk, so YMMV.
We use LAMP and our site gets > 30,000 hits per SECOND on two servers and 5
pools.

I've been working on a PHP/Javascript Cookie Notify (Including multiple
language support). Now I have one small problem, when session_start() is not at
the top, the cookie message works as it should be.
Now I am trying to add session_start(); at the top, as this will load the
current language file the visitor has set it to. But then the cookie message
will not show.
I've cleaned all my cookies, and still can't get it to work ...
I've put up a small code on jsFiddle, but when session_start(); is at the top,
it launches correctly in jsFiddle. which can be viewed (here).
Does anyone know what i'm doing wrong? And would you be able to explain me what
I am doing wrong?
Thanks
