To identify the Go functions consuming the most CPU in your GKE-deployed application for optimization, what steps should you take?

(Optional code block if applicable, corrected for syntax/typos):

// Example placeholder for potential code needing correction  
func highCPUFunction() {  
    for {  
        // CPU-intensive operations  
    }  
}  

// Example placeholder for potential code needing correction  
func highCPUFunction() {  
    for {  
        // CPU-intensive operations  
    }  
}
