Visual Studio Profiler: Performance Optimisation

Visual Studio Profiler:  Performance Optimisation

This week i learnt a new tool within visual studio to optimise a program performance by pinpointing bottlenecks in your program. This tool is very easy to use and can help speed up the program execution time by allowing you to fix bottlenecks in the program.

My Test Program that's currently taking 10 milliseconds to execute

This is the first performance report it shows the writeline() function is taking 41% of the whole execution time.

First Test

This is the second test report and you can see straight away removing the writeline() function took the execution time from 10 milliseconds to 5 milliseconds, That's simple bottleneck removal cuts the execution time in half. 

I know removing all slow code is not possible sometimes but this tool doesn't give you a suggestion of what to use instead but by highlighting the bottlenecks in a program it helps the programmer choose an alternative method or function that executes faster therefore improving the performance of the code overall.
