How can I implement performance logging in Golang?

How can I implement performance logging in Golang?

You can use the built-in log package along with time to measure execution time. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

package main

import (
    "fmt"
    "log"
    "time"
)

func main() {
    start := time.Now()
    // Your code here
    time.Sleep(2 * time.Second) // Simulating work
    elapsed := time.Since(start)
    log.Printf("Execution time: %s", elapsed)
}

What if I want to log additional information like memory usage?

You can use the runtime package to get memory statistics. Would you like to see how to integrate that?
