Issue/Introduction
NetQoS Performance Center has experienced increasing slowness when loading pages with graphical views.
Cause
NPC uses a graphics folder to save temp files of graphics loaded by NPC. These may be retained for a long time. Many files may build up in the directory, especially if an auto-refresh is enabled with many graphical view. This directory is located here:
<InstallDirectory>\portal\WebSite\Graphics
Windows Server doesn't perform well when the file count gets very high.
Environment
Resolution
If you have a very high file count in this folder, it is safe to delete these .PNG files from the folder. After doing so, you should see a marked performance increase.
Additional Information
We have observed file counts as high as 1.2 million in this folder. NPC views were taking as long as 45-60 seconds to load.
