Opcache revalidate freq config in php.ini

Question

If I'm setting this config in php.ini file:

opcache.revalidate_freq = 0

Will it still be better than disable Opcache system?

Because in my opinion, it will check for file updates every request, so it like the Opcache is disabled.

Answer 1

It will check the timestamp on every request, if the timestamp is unchanged it will serve the file from cache, so you are still benefiting from the opcache.

Answer 2

This is how soon opcache will check whether the php file has changed, as far as I know. I use 30 seconds:

opcache.revalidate_freq=30

what you're referring to is likely the on / off for that function:

opcache.validate_timestamps=1
