Performance Troubleshooting (ANTS tool)

it happened once that a client raise an issue regarding to poor performance at certain area on an application that I was working on. That area was working perfectly on my environment, but at their environment it was not like that. I could not duplicate their environment locally because of security restrictions rules we have. Tracing code and do debugging was not helpful. Thus I decided to look into a tool that will help me on this mission.

I found a very nice tool that help me very much on tracing and figuring out the bottleneck on my application, that tool is called ANTS from Red-Gate. I strongly recommend to try this tool.
