I'm trying to tune the performance of my application. And I'm curious what methods are taking the longest to process, and thus should be looked over for any optimization opportunities.
Are there any existing free tools that will help me visualize the call stack and how long each method is taking to complete? I'm thinking something that displays the call stack as a stacked bar graph or a treemap so it's easy to see that MethodA() took 10 second to complete because it called MethodB() and Method(C) that took 3 and 7 seconds to complete.
Does something like this exist?
Yes, they are called performance profilers. Check out RedGate ANTS and JetBrains' dotTrace, not free but pretty cheap and way better than any free alternative I have seen.
