You may find that you need to increase the opcache.memory_consumption or some other setting for Opcache. To do so, you will need to create a custom configuration file with the settings you’d like to build Opcache with that DirectAdmin’s CustomBuild will recognize. Then, copy the original opcache.ini file over to this custom/ directory.
Java is one of the most popular programming languages used to build different types of applications and systems.
There are two different implementations of Java, OpenJDK and Oracle Java, with almost no differences between them, except that Oracle Java has a few additional commercial features. Oracle Java License permits only non-commercial use of the software, such as personal use and development use. OpenJDK is an open-source implementation of the Java Platform.
Redis is an open source key-value cache and storage system, also referred to as a data structure server for its advanced support for several data types, such as hashes, lists, sets, and bitmaps, amongst others. It also supports clustering, which makes it often used for highly-available and scalable environments.
In this tutorial, we’ll see how to install and configure an external Redis server to be used as a session handler for a PHP application running on CentOS 8.
WP-CLI wordt niet voorgeïnstalleerd op je hostingpakket. Daar zijn eigenlijk twee simpele redenen voor. Niet iedereen met een hostingpakket wil per se WordPress gebruiken. Wel WordPress installeren betekent daarnaast niet dat iemand ook meteen WP-CLI wil. Gelukkig is zelf WP-CLI installeren zo gebeurd en daarna ook makkelijk bij te werken wanneer nodig.
The Mail Queue will show you, of course, all the email messages that are in the queue. If a user on your server has issues with the emails then you should check the DirectAdmin Mail Queue.
Just like gzip, Brotli is also a compression algorithm. It is developed by Google and serves best for text compression. The reason being, it uses a dictionary of common keywords and phrases on both client and server side and thus gives a better compression ratio. The advantage for Brotli over gzip is that it makes use of a dictionary and thus it only needs to send keys instead of full keywords. It is supported by all major browsers. Fewer bytes transferred not only leads to faster page load but also helps in reducing costs of Content Delivery Network (CDN).

Free & open source, high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.
Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.
Memcached is simple yet powerful. Its simple design promotes quick deployment, ease of development, and solves many problems facing large data caches. Its API is available for most popular languages.
Ioncube loader for PHP 7 is not yet implemented in Installatron plugin installer. You will get a error 404 when the install script is downloading the ioncube loader. To fix this, you need to install PHP 5.5, that will only be used for Installatron.
Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. Because of Memcached is not well maintained (not compatible with PHP 7) and could be considered as end-of-life, Redis should be a good alternative for Memcached.
Redis is a single-threaded server. It is not designed to benefit from multiple CPU cores. People are supposed to launch several Redis instances to scale out on several cores if needed. It is not really fair to compare one single Redis instance to a multi-threaded data store. Redis can also be configured as a cluster.
