We have the Sitewide plugin Version 0.4.1.1 installed on WordPress 3.2.1
This has been in place for a few months and we are replicating posts nicely, without any reported performance issues.
Just 2 days ago an end user reported a performance issue in updating any post. It was taking in the range of 30 seconds to save an update to a post.
This issue was not present for a separate WordPress Network that did not have sitewide tags activated (on the same WordPress install)
We network disabled the sitewide tags plugin and performance improved dramatically when updating a post.
I reactivated the plugin and expected bad performance, but performance remains great.
Does anyone have insight into this issue? Is it possible that some value was reset when the plugin was deactivated and reactivated.
