Can you explain what the profiling tool Pprof is and how it is used in development?

Pprof is a profiling tool built into the Go language that allows collecting and analyzing application performance data, such as CPU usage, memory, blocking, and other metrics.

How it is used:

• The net/http/pprof package is imported into the application code, which automatically registers HTTP endpoints for profile collection.
• The application is run with pprof enabled.
• Using the go tool pprof command or a web interface, you can connect to the application and obtain profiles.

Example of connecting pprof in Go:

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

func main() {
    go func() {
        log.Println(http.ListenAndServe("localhost:6060", nil))
    }()
    // rest of the application code
}

After starting, you can get a CPU profile with the command:

 go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30

Pprof helps identify bottlenecks in performance and optimize the application.
