Edge Index Plugin appears to be causing some slow performance.

XMLWordPrintable

      Creating and saving a page with the Edge Index Plugin enabled can take around 1 second or more. Disabling this plugin appears to increase performance, and Performance Profiling logs support this, in that some behaviour which happens with the plugin is enabled does not appear to happen when it is disabled.

      This is the profiling with the plugin enabled:
