Hi @vlee

Or

APCu is designed to be used alongside OpCache so yes it does help and work well with it. There's a really good stackoverflow article that describes this here: What is userland caching APCu extension in PHP?

Thanks!

When doing the opcache php code cache, the apcu makes object cache.

Combined use improves performance.

However, in apcu installation in cpanel environment, php doesn't do any caches although it appears in info. There is no cache entry when I install and check the apc.php file for monitoring. I couldn't figure out why this problem was caused.
