How to benchmark:
|
|
|
|
- There is a test in the `main_test.go` file containing a benchmark loop
|
|
- run the command `go test -bench . -run ^$` to run only the benchmark test
|
|
- you can make the bench tool run more iterations of the benchmark using a flag on the command:
|
|
`go test -bench . -benchtime10x -run ^$`
|
|
|
|
- to profile the program run `go test -bench . -benchtime=10x -run ^$ -cpuprofile cpu00.pprof`
|
|
The above command will generate two files that will be used for profiling the program
|
|
|
|
To use the generated files for profiling you have to run:
|
|
`go tool pprof cpu00.pprof`
|
|
|
|
For memory
|
|
`go test -bench . -benchtime=10x -run ^$ -memprofile mem00.pprof`
|
|
|
|
`go tool pprof -alloc_space mem00.pprof`
|
|
|
|
This will start an interactive cli session where you can view more details about the functions running in the program
|
|
Inside that interactive cli session you can use the `top` and `list` commands to see details of the functions that are running
|
|
|
|
|
|
For tracing:
|
|
|
|
`go test -bench . -benchtime=10x -run ^$ -trace trace01.out`
|
|
|
|
`go tool trace trace01.out` |
