Has there been any changes made since 7.1.8 that could improve the accuracy of this figure?  
(see attached file) Or is this coming directly from what the Java engine is reporting?  
…BTW it normally hums along between 10-30%

I believe this is the cumulative CPU usage for Ignition, across all cores. If you have a quad core server, and are using 50% on all cores, itll show 200%. Thats what I noticed in my findings, but I could be wrong.
