PHP - Web Services Measuring Bottleneck
I have currently developed a script that consumes a web service. It is running real slow. I think this is due to the web service provider. How do I diagnose/measure this?
Similar TutorialsI have questions but I also have some good info to share about putting your software in the cloud. The situation: Some of you may have read about the nightmare stories. A developer had a infinite loop in his code that ran all night. This code did things inefficiently that devoured CPU in each iteration. This developer, greatly skilled, opened his email the next morning and saw a email bill from his cloud provider totaling for $75K. True story. Most cloud providers let you define CPU usage thresholds that, when breached, send you a warning but these thresholds, if I understand them, are per account. It would seem the claim that cloud resources are available in whatever amounts you need, CPU, disk space, enough RAM to never have to wait on a page faults, etc... the claim that the cloud provides you with infinitely elastic resources in an "all you can eat for one price" contract smells just a like a little like 💩 I did cloud development for many years with ServiceNow starting when it was a help desk and I watched it evolve into one of the best cloud development platforms out there. At one customer site I installed and managed it it out of the cloud and saw its insides and I can tell you its core code is not so terribly efficient. IMHO the cloud DOES take away 90% of a developer's worries about app performance.. If you call ServiceNow tech support and your problem is diagnosed as a performance issue with your code the first thing they will ask you is "did you follow the developer best practices"? They will politely say "sorry. Here's a link to them implying "fix your code". Questions: PHP Functions that devour CPU and where there is a better way? What PHP functions or code techniques waste CPU? I am using similar_text and it does the job but it is slow. Better way? What is the best way to measure CPU used by a PHP script or by a particular code module, defined as a set of related functions that fulfill a common purpose or by a single line of code? The purpose being to identify inefficient modules of code and improve them and even if the code is damn near perfect then at least can know what code modules are the most expensive. CPU killin users (and developers too), how can they be identified? I need to store data on cumulative CPU usage for any of the above and compare it with the free amount they give you and warn CPU hogs before they breach a threshold and generate $75K bills that were not in the plan. Any info you have on avoiding surprise $75K CPU bills from a cloud provider are welcome
It would seem the Hello all. Is it possible to have a link that can start and stop a service on the web server? It is a windows 2003 server. Thanks, Mike This topic has been moved to Other Web Server Software. http://www.phpfreaks.com/forums/index.php?topic=305914.0 I want to purchase cloud servers from DigitalOcean, however I know very little about managing and maintaining servers (I just develop the websites). I know what I need without knowing how to do it. I read the conditions for hosting at PHP Fog, and they state that I can't use session variables as such variables are not copied between servers. Therefore I changed session variables for login info, language selection etc to cookies. Hence my own code is now free from session varibables, but Zend that I use for e.g. OAuth is not. Is it typical that cloud hosting providers disallow session variables for the above reason, or are there others that can handle such replication between servers? If not, is work going on to remove use of session variables from popular frameworks? Cheers, Anders hello, i am hoping someone can help, been working on my own mvc with help from tutorials, but i am stuck with this error: Fatal error: Class 'services' not found in C:\xampp\htdocs\Workspace\Cyberglide\libs\Bootstrap.php on line 27 were it says services that changes when i type a different item in the url, loads the error page but says that at the bottom of the page. hoping someone can help me where i gone wrong: Code: [Select] <?php class Bootstrap { function __construct() { $url = isset($_GET['url']) ? $_GET['url'] : null; $url = rtrim($url, '/'); $url = explode('/', $url); //print_r($url); if (empty($url[0])) { require 'controllers/index.php'; $controller = new Index(); $controller->index(); return false; } $file = 'controllers/' . $url[0] . '.php'; if (file_exists($file)) { require $file; } else { $this->error(); } $controller = new $url[0]; $controller->loadModel($url[0]); // calling methods if (isset($url[2])) { if (method_exists($controller, $url[1])) { $controller->{$url[1]}($url[2]); } else { $this->error(); } } else { if (isset($url[1])) { if (method_exists($controller, $url[1])) { $controller->{$url[1]}(); } else { $this->error(); } } else { $controller->index(); } } } function error() { require 'controllers/error.php'; $controller = new Error(); $controller->index(); return false; } hope someone can help, many thanks guys.
