Details edit

Sets how often site statistics should be updated.

Set this to an integer to only do synchronous site_stats updates one every this many updates. The other requests go into pending delta values in $wgMemc . Make sure that $wgMemc is a global cache. If set to -1, updates only go to $wgMemc (useful for daemons).
