Confluence 4.0 : Server Hardware Requirements Guide
This page last changed on Jun 07, 2011 by pwatson.
Server administrators can use this guide in combination with the free Confluence trial period to evaluate their server hardware requirements. Because server load is difficult to predict, live testing is the best way to determine what hardware a Confluence instance will require in production. Peak visitors are the maximum number of browsers simultaneously making requests to access or update pages in Confluence. Visitors are counted from their first page request until the connection is closed and if public access is enabled, this includes internet visitors as well as logged in users. Storage requirements will vary depending on how many pages and attachments you wish to store inside Confluence. Minimum Hardware RequirementsOn small instances, server load is primarily driven by peak visitors. 5 Concurrent Users

Example Hardware SpecificationsThese are example hardware specifications for non-clustered Confluence instances. It is not recorded whether the RAM refers to either total server memory or memory allocated to the JVM, while blank settings indicate that the information was not provided.
Server Load & ScalabilityWhen planning server hardware requirements for your Confluence deployment, you will need to estimate the server scalability based on peak visitors, the editor to viewer ratio and total content.
Confluence scales best with a steady flow of visitors rather than defined peak visitor times, few editors and few spaces. Users should also take into account:
As mentioned on the documentation for Operating Large or Mission-Critical Confluence Installations, some important steps are loadtesting your usecase and monitoring the system continuously to find out where your system could do better and what might need to improve in order to scale further. Maximum Reported UsagesThese values are largest customer instances reported to Atlassian or used for performance testing. Clustering for load balancing, database tuning and other performance tuning is recommended for instances exceeding these values.
Hard Disk RequirementsAll wiki content is stored in the database, while attachments use either the database or filesystem. For example, the wiki instance you are reading now uses approximately 1 GB of database space and 9.4 GB of disk space. Here is a breakdown of the disk usage requirements for this wiki, as at December 2008:
Size of selected database tables
Note: not all database tables or indexes are shown, and average row size may vary between instances. Size of selected home directory components
Note: not all files are shown, and average file size may vary between instances. Private & Online ComparisonPrivate instances manage their users either internally or through a user repository such as LDAP, while online instances have public signup enabled and must handle the additional load of anonymous internet visitors. Please keep in mind that these are examples only, not recommendations:
Professional AssistanceFor large instances, it may be worthwhile contacting an Atlassian partner for expertise on hardware sizing, testing and performance tuning. Simply contact a local partner directly or email our partner manager for a recommendation. Related Pages
