When comparing projects with more than 5,000 activities, the Visualizer application Schedule Comparison takes 15 Minutes to complete.

The issue can be reproduced at will with the following steps:

  1. Select Tools > Schedule Comparison
  2. Select 'Open From Existing'
  3. Select Compare name and select 'Draw'



The slow performance of schedule comparison does not necessarily affect large projects.
Projects with ~1,000 activities, taking approximately 2 minutes, were reduced to 20 seconds after applying the patch.
