Manual:Rate limits

MediaWiki applies rate limits to some user actions, particularly ones that modify content or require a lot of resources.

Configuration

A rate limit can be applied for any user right. The actual values of the rate limits can vary per wiki configuration via these parameters:

• $wgRateLimits
• $wgAccountCreationThrottle
• $wgPasswordAttemptThrottle

If an account has the noratelimit right (such as an account in the Bot or Admin group), these rate limits don't apply. To see the limits that apply to you, use the user info API module, for example:

api.php?action=query&meta=userinfo&uiprop=ratelimits&format=json [try in ApiSandbox]

Bots using OAuth

To bypass configured rate limits using the noratelimit right, a bot that uses OAuth must ensure that its OAuth client includes the highvolume grant.

Concurrency limits

Some actions also have a maximum number of requests that can happen at the same time. These concurrency limits are controlled by $wgPoolCounterConf and are disabled by default.

Limits

Limits apply only to actions that users are allowed to perform based on their user rights. Here are some examples of limits on common actions and how they are applied on Wikimedia wikis. For a complete list of default limits in MediaWiki, see $wgRateLimits.

Action	Minimal user right	MediaWiki default ratelimits	Wikimedia wikis with custom ratelimits
edit	* (all)	8 per minute	Turkish Wikipedia: lower limit for new and logged-out users Wikimedia Commons: higher limits for all users, including extra high limits for trusted user groups
	autoconfirmed	90 per minute
move	* (all)	2 per 2 minutes	Higher limits for trusted groups: Wikimedia Commons, Arabic Wikipedia, English Wikipedia, English Wikibooks, Korea Wikipedia, and Ukrainian Wikipedia

upload	* (all)	8 per minute	Wikimedia Commons: higher limits for trusted user groups
rollback	* (all)	5 per 2 minutes	None
