I'm looking for a way to actually stop plugins from querying their developers sites to find out if there is a new version.
From running New Relic on a client site I'm working on I can see that outside calls to developer sites (such as WPMUdev) take a hell of a long time to complete, and must be tying up CPU time that would be much better utilised by actual processes that are needed.
Needless to say, there is no reason for a live site to ever be updated directly, so I'm looking for a way to stop these queries happening. Updates can then be done on a local copy and pushed via GIT.
TIA, Thall.
