Memory Requirements

Memory requirements for running an ownCloud server are greatly variable, depending on the numbers of users and files, and volume of server activity. ownCloud officially requires a minimum of 128MB RAM. But, we recommend a minimum of 512MB.

Consideration for low memory environments

Scanning of files is committed internally in 10k files chunks. Based on tests, server memory usage for scanning greater than 10k files uses about 75MB of additional memory.

Database Requirements

The following are currently required if you’re running ownCloud together with a MySQL or MariaDB database:
