I am doing load testing for my Application, I am running 250 virtual users to access my website.I am using HP Load Runner.
After 40 minutes of load testing, I checked # of Exceptions thrown counter, it is 11000 exceptions.
How bad is that? what is the recommended fix?
You shouldn’t be throwing so many exceptions. Check if these are exceptions like NullReference , ArrayOutOfBounds, ArgumentException etc. These must never occur in your code.
Try to categorize the type of exceptions that are coming and from where they are coming.
Read this wonderful article by Jon Skeet on how costly exceptions are in .Net: http://www.developerfusion.com/article/5250/exceptions-and-performance-in-net/
