If disabled, all PHPDoc
comments are dropped from the
code to reduce the size of the
optimized code.
If enabled, a fast shutdown
sequence is used for the
accelerated code
A bitmask, where each bit
enables or disables the
appropriate Optimizer+ passes
Enables or disables the
optimization passes that may
take significant time, based on
an internal runtime calculation
External Configuration File: Optimizer+ blacklist file
The Optimizer+ blacklist file is a text file that holds the names of files that should not be accelerated. The
file format is to add each filename to a new line. The filename may be a full path or just a file prefix (i.e.,
/var/www/x blacklists all the files and directories in /var/www that start with 'x'). Files are usually triggered
by one of the following three reasons: 1) Directories that contain auto generated code, like Smarty or
ZFW cache. 2) Code that does not work well when accelerated, due to some delayed compile time
evaluation. 3) Code that triggers an Optimizer+ bug.
