PHP enables opcache to improve Code Performance

APC is the best-performing code cache in PHP5.4 and earlier versions. However, after PHP is upgraded to 5.5 or above, APC is no longer valid. The Zend OpCache extension is required.

The configuration command is 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 memory size, also adjustable Opcache. interned_strings_buffer = 8 ; Maximum number of cached files Opcache. max_accelerated_files = 4000 ; Check for file updates every 60 s Opcache. revalidate_freq = 60 ; Enable quick close. Enabling this will increase the memory receiving speed when the PHP Request Shutdown is enabled. Opcache. fast_shutdown = 1 ; Do not save file/function comments Opcache. save_comments = 0

Actual Performance Comparison:

The following figure shows that opcache is not enabled in actual tests:
