Activate the Developer Dashboard using the SharePoint Object Model:-
using Microsoft.SharePoint.Administration;
SPWebService svc = SPContext.Current.Site.WebApplication.WebService;
svc.DeveloperDashboardSettings.DisplayLevel =
    SPDeveloperDashboardLevel.Off;
svc.DeveloperDashboardSettings.Update();

SPMonitoredScope to track performance in your applications:-
 using (new SPMonitoredScope("Monitoring"))
{
    Controls.Add(new Literal { Text = "When the awesomeness is flying... " });
               
    using (new SPMonitoredScope("Sub-Monitoring"))
    {
        Controls.Add(new Literal { Text = "Hello this is --Sub-Monitoring! " });

        using (new SPMonitoredScope("Sub-Sub-Monitoring"))
        {
            Controls.Add(new Literal { Text = "<br/>Hello this is Sub-Sub-Monitoring!" });
        }

        using (new SPMonitoredScope("Sub-Sub-Monitoring_1"))
        {
            Controls.Add(new Literal { Text = "Hello this is Sub-Sub-Monitoring_1" });
