Increased performance by 10% with enabling opcache file caching

[choward420]

Not sure how to approach this but was hoping you could include in the build.

Changed /etc/php81/conf.d/opcache.ini

FROM:
opcache.enable=1
opcache.enable_cli=1
opcache.fast_shutdown=1
opcache.memory_consumption=256
opcache.interned_strings_buffer=16
opcache.max_accelerated_files=10000
opcache.revalidate_freq=60

TO:
opcache.enable=1
opcache.enable_cli=1
opcache.fast_shutdown=1
opcache.file_cache="/tmp/cache/"
opcache.file_cache_only=0
opcache.file_cache_consistency_checks=1
opcache.memory_consumption=256
opcache.interned_strings_buffer=16
opcache.max_accelerated_files=10000
opcache.revalidate_freq=60

Ran the following based off of librenms performance recommendations:
mkdir -p /tmp/cache && chmod 775 /tmp/cache && chown -R librenms /tmp/cache

opcache.revalidate_freq=60 should be removed and opcache.validate_timestamps=false should be added.

Correction to my statement above, sudo is not installed in the docker so I ran the following:
mkdir -p /tmp/cache && chmod 775 /tmp/cache && chown -R librenms /tmp/cache

10%

Can you post your benchmarks affirming this supposed percentage?

80+ pollers running on different platforms, some virtualized, some containers, some virtualized running containers, etc. all experienced a ~10% decrease in devices polled when I upgraded to PHP8. After making the above changes, everything went back to the way it was. This wasn't an enhancement from the way it was, it just got me back to ground zero.
