Software for testing applications to increase performance

Question

I'm searching for software to do benchmarking, analysis, performance of code and apps. Something like Intel VTune.

Can anyone give me some names, free or payed, targeting c# apps.

thanks

Answer 1

Redgate Performance Profiler

...their Memory Profiler will undoubtedly help as well.

Answer 2

It sounds like you have multiple purposes.

If you want to monitor the performance health of programs, benchmarks and profilers that measure are probably what you want.

If you need to make a program faster, and you have the source code for it, I think your best bet is to get something that samples the call stack and gives you line-level percent of wall-clock time. For this, don't look for high precision of timing. Look instead for high precision of pinpointing code that is responsible for high percentages of time. Especially in larger programs, these lines are function or method calls that you can find a way to avoid. Don't fall into the myth of thinking that the only problems are hotspots where the program counter lives, and don't fall into the myth that all I/O is necessary I/O.

There's a totally manual method that a few people use and works very well.
