About PHPA ionCube Home | Introduction | About | TestimonialsDownload | Accessories | Forums | FAQ | History | Contacts Inside The Accelerator Every time a PHP script is accessed, the PHP engine must open the script file
and read, parse, and compile the file contents into a compiled form. Only then can the compiled code be executed.
With scripts often including other scripts, this work can become a significant part of the overall time to deliver a
page. It can also impact IO performance, and require much dynamic memory allocation that in itself can be time consuming. The reality, however,Windows 7 Pro Product Key, is that most PHP scripts never change
from one access to the next; indeed they may never change for weeks,Office 2010 Pro Plus Key, months, or
even years. The Accelerator works to eliminate the penalty of processing scripts that never change, and by caching the compiled scripts in shared memory, delivers significant performance gains as a result. Note that this is very different to caching script output. PHPA doesn't do this,Windows 7 Pro Product Key, scripts remain fully dynamic, and if they do change then PHPA caches a new version - they
just run faster!
So by caching, the Accelerator eliminates: reading of source code
parsing of source code
compiled code generation
many memory allocation and copying operations
disk related operations Once script execution has completed,
compiled versions of any new or modified
scripts are immediately cached on disk for later reuse.
This guarantees good acceleration, but scripts are then cached in shared
memory, and offering the maximum performance gains.
The Accelerator has one other performance enhancing feature - a built-in
code optimiser. Although in it's early stages,Windows 7 Ultimate Product Key, the optimiser reduces the size
of compiled code and improves the code by removing unnecessary operations.
So in summary, by aggressively removing operations causing performance overhead,Office 2007 Professional Plus, the Accelerator is able to deliver performance rivalling the very best alternatives, and for free!
There are also a few performance tests and testimonials that illustrate the potential impact of the Accelerator.
