When we wish to take a look at the speed of our program, the best technique we can employ is profiling. Profiling automatically samples your running application while it is executing; and then we can compute that data, such as the running time of a particular function, into a statistical summary called a profile.
Go supports three different types of profiling:
- CPU: Identifies the tasks which require the most CPU time
- Heap: Identifies the statements responsible for allocating the most memory
- Blocking: Identifies the operations responsible for blocking Go routines for the longest time
If we would like to enable profiling on our application, we can do one of two things:
- Add import "net/http/pprof" to your startup file
- Manually start ...
