Use Process Explorer To Quickly Identify Performance Bottlenecks In ASP.NET Web Applications
 Process Explorer is my best friend when I need to quickly identify potential performance bottlenecks for ASP.NET web applications. When I am called onsite I have it always with me.
It served me well recently so I thought it'd be proper to show my appreciation to the tool and to the creator, Mark Russinovich, by sharing how I use it. Every time I am called onsite to the customer's, first thing I ask to install ...ehm... copy the tool to the server in question. It usually shows hot spots right away and helps making assumptions and decisions. |

CPU Usage History
This view helps to spot "unusual" activity for ASP.NET Web Application. When I see "too much" red color in this view I start asking question "Why Managed .Net Code performs privileged operations?" From my observations it mostly caused by excessive usage of threading.
Private Bytes Memory
This view has become my favorite recently as I was involved in few cases with memory leakage. I think the picture is self explanatory.
I/O Bytes History
This view helps me spotting potential I/O bottlenecks.
