What is profiling in Go? Have you used pprof?

Profiling in Go is the process of analyzing the program's operation to identify bottlenecks in performance, memory usage, and other resources. The pprof tool allows collecting and visualizing profiling data such as CPU profile, heap profile, locks, and goroutines.

Example of using pprof:

import (
    "net/http"
    _ "net/http/pprof"
)

func main() {
    go func() {
        log.Println(http.ListenAndServe("localhost:6060", nil))
    }()
    // Main program code
}

Running the program with this code allows you to access profiles at http://localhost:6060/debug/pprof/. This helps analyze performance and optimize the application.
