Hardware Requirements

Hardware requirements for OroCommerce depend on the amount of data stored in the application and on the number of users working with the application concurrently.

The following information describes the minimum and the recommended hardware requirements for a generic types of deployment. Actual requirements may vary depending on your system configuration, data, and service level requirements.

Community vs Enterprise Edition

OroCRM Community Edition supports deployments for individual use only and is not recommended for production systems with more than one user due to the potential data collisions and significant performance degradation when using search.

General Database Requirements

For both MySQL and PostgreSQL, there is limit of concurrent users and the database size. MySQL utilizes less CPU time and it can be installed on the same server with Web Server. MySQL is faster for databases less than approximated 300 thousands of records.

PostgreSQL can utilize full CPU, therefore the recommendation is to have a dedicated server with PostgreSQL. PostgreSQL is recommended for databases with more than a million or several million records.

Database server memory size

For both MySQL and PostgreSQL, the memory size should be equal to the database physical size (or more). The default MySQL configuration exceeds the default PostgreSQL configuration, however, they both require optimization. Optimization will depend on the available memory and the estimated number of concurrent users.

CPU

For CPU, the recommendation is to have 7 to 9 concurrent users per one CPU core if database server is hosted in a separate environment.

Web Server Memory Size

The approximate web server memory size is 300 Mb per user.

Cache Provider

Redis is recommended as a cache both for Community and Enterprise Edition versions. Redis decreases I/O disc operations and increases application performance in a number of times. Redis server should be shared on the same Web Server.

Search Engine

ElasticSearch search engine is recommended for Enterprise version only. It increases search performance in several times. Note, however, that ElasticSearch requires additional maintenance and environment resources.

Daemon

JMS Daemon and its jobs should be hosted on a separate server. To share cache, it should connect to Redis hosted on a Web Server machine. Such configuration does not affect performance of web users.
