Performance Optimization: PHP

opcache

Enable the Zend extension opcache in PHP. In the php.ini, we recommend the following configuration:

opcache.enable=1
opcache.memory_consumption=512
opcache.max_accelerated_files=100000
opcache.validate_timestamps=1
opcache.revalidate_freq=2
opcache.optimization_level=0x7FFF9FFF

Up to BlueSpice 4.2.x only  -v4.2.x: In addition, you should include the BlueSpice configuration files ( extensions/BlueSpiceFoundation/config/*) in the Opcache blacklist (opcache.blacklist_filename). You can find more information in the official PHP documentationfor configuration.php.

This config-file is no longer available from version 4.3.

zlib

Activate the extension zlib. In the php.ini we recommend the following configuration:

zlib.output_compression = On
zlib.output_compression_level = 9

You can find more information in the official PHP documentation for zlib.
