just added a check in Profiler's render method to also look at Config::get('application.profiler') as laravel allows changing config during runtime. This allows turning off profiler for certain actions

Track the running time of a function
Profiler::time(function(){});
Profiler::time(function(){}, 'name');

Track a stopwatch style timer throughout your app
Profiler::tick('name');
Profiler::tick('name', function($timer){});
