Scalability in PHP Optimizing your code, and building your apps to scale Ian Selby Senior Web Developer at Aptana www.aptana.com

So, how do I … at least how do I do it in PHP? Build a Scalable App?

We can optimize in three places:

Now that my code is optimized, How do I make it run faster?

Easy! Use Opcode Caching! Duh!

What is opcode caching? Opcode caching optimizes PHP intermediate code and caches data and compiled code from the PHP bytecode compiler in shared memory.

What is opcode caching? Basically, your code is pre-compiled, and then stored in memory. So, it runs faster.

APC – Alternative PHP Cache http://pecl.php.net/apc http://php.net/apc

But, it gets better… You can actually cache your own data with APC! Let’s take a look at that now…

Source code available at gen-x-design.com

So, my code is gooder and cached.. What can I do to speed up my database stuff?

Cool, my databases are tuned… What kind of infrastructure should I set up?
