Faster php with zend optimizer?

janneke

Hello all,

I've just got a new host and i runned
phpinfo() immediately. I've found out that
the host has zend optimizer installed.

I already figured out that i don't need
anything to change to get my php scripts
functioning with zend optimizer.

But can i "help" zend optimizer to optimize
my code? What i mean are there rules/tips
or code lines which zend optimizer
optimize more then others?

My goal is to make my scripts even more
faster with the help of zend optimizer.

Cheers!

Since the optimizer works with runtime-compiled code, rather than with source code directly, probably the best thing you can do is write clean, efficient scripts, and it sounds like you do that already.

From what I understand, Zend Optimizer does not actually speed up the code - I think the name is a little misleading. You would need their Cache for that. You should look at tools like mmCache if you want to speed up the loading of your code

A look at Zend's web site suggests otherwise to me.

The third-party tests I've seen show throughput time decreases of anywhere from 5 to 40% with the optimizer installed, depending on the kinds of operations. Zend claims "Increases runtime performance up to 40%", which is mathematically meaningless, but I guess they mean the same thing.

I'm sure we all know the difference between the Zend Optimizer and the Zend Accelerator. The optimizer is free and, afaik, installed by most hosting companies. The accelerator is not free and, afaik, installed by some hosting companies.

Please forgive another gratuitous note: sometimes people think that making code "smaller" increases performance. This is not necessarily true, for nearly any language. As for the optimizer, Zend say in its technical FAQ, "The factors that tend to improve run-time speed are not necessarily the same as those that tend to decrease file size."

I'd be interested in seeing these 3rd party tests. You got any immediate links to any (being lazy as I am 🙂 )

Thanks
