Help:$smwgEnabledDeferredUpdate

is a configuration parameter that sets that updates to pages are added to the job queue and executed after page edits. It was introduced in Semantic MediaWiki 2.4.0 thus obsoleting .CiteRef::gh:smw:1435

The default setting " " which is the recommended setting will make Semantic MediaWiki act for update operations as it is done for a lot of update operations with MediaWiki itself for versions 1.26 and later. This should improve page responsiveness for purge and move actions significantly. This configuration parameter should not influence wikis using MediaWiki 1.25 and lower. In case some unexpected behaviour is being observed the deferred updates can be disabled by changing the setting to " ".
