PHP Open Opcache improve code performance

APC is the best performing code cache in PHP5.4 and the following versions. However, after the PHP upgrade to 5.5 and above, the APC is no longer valid. You need to use the Zend Opcache extension.

The configuration directives are as follows:

?

1 2 3 4, 5 6 7 8 9 10 11 12 13 14 15

[Opcache] zend_extension=opcache.so opcache.enable_cli=1, shared memory size, which can be adjusted according to your needs opcache.memory_consumption=256; Interned string's memory size, also adjustable opcache.interned_strings_buffer=8; The maximum number of cached files opcache.max_accelerated_files=4000; 60s Check for file update opcache.revalidate_freq=60; Turn on fast shutdown, open this shutdown the speed of the memory will be increased when PHP Request is opcache.fast_shutdown=1; do not save the file /function Annotation Opcache.save_comments=0
