Jpgraph Accelerator nusphere Installation Configuration Tutorial

As mentioned in the previous Jpgraph tutorial, the way to improve jpgraph performance is to install the PHP accelerator in addition to using the Jpgraph caching system. In fact, installing an available PHP accelerator is one of the best ways to increase the performance of a large and complex PHP script. Jpgraph supports Nusphere phpexpress accelerator.

To take advantage of this accelerator, you must install the version of the encoding library that the accelerator uses. This version includes the Professional Edition directory src-encoded/directory.

If you have a professional version of the Jpgraph class library, there is no reason not to use the accelerated version of the library. It lowers the load on the server and significantly reduces the elapsed time of the chart script. In addition, it will also reduce the memory requirements.

Nusphere Phpexpress also implements a caching mechanism, which means that scripts that are often executed will be saved in memory to avoid the need for time to read from disk every time. This also applies to coded and non encoded script files.

　　Installation Configuration Nusphere phpexpress Accelerator

2. If your PHP running environment is deployed under Windows, add a line

If your PHP operating environment is deployed under UNIX, Linux or Mac OS, add a row

1	Zend_extension=/full/path/to/phpexpress-php-x.x.so

3, copy Phpexpress-php-x.x.dll or phpexpress-php-x.x.so to php.ini specified PHP extension directory
