Check Your Mysql Server Performance with MySQLTuner -- Debian Admin
by camel
& 1 other
MySQLTuner is a script written in Perl that will assist you with your MySQL configuration and make recommendations for increased performance and stability. Within seconds, it will display statistics about your MySQL installation and the areas where it can be improved.
It’s key to remember that MySQLTuner is a script which can assist you with your server, but it is not the solution to a badly performing MySQL server. The best performance gains come from a thorough review of the queries sent to the server, and an evaluation of the MySQL server itself. A qualified developer in your application’s programming or scripting language should be able to work with a MySQL database administrator to find improvements for your server. Once the server and application are optimized well, you may need to consider hardware upgrades to the physical server itself.
This is a really useful tool for helping to optimize MySQL performance.Understanding the various my.cnf variables and how they affect performance can seem really complicated but this tool takes some of the pain away and makes it easier to understand the effects of each variable.It is especially useful to be able to see the global memory usage, memory usage per thread and the maximum possible memory usage - that is really valuable information that is otherwise complex to calculate.

Script pour optimiser les images d'un site (eZ Publish, Linux, Online Editor, Performances, shell, Web)
by camel
& 1 other
L'optimisation des images est une manière simple et peu coûteuse d'améliorer les performances d'affichage d'un site au premier chargement (avec le cache navigateur vide) sans trop de problèmes. Smush it! a remis ce sujet à la mode et permet de voir facilement les images à optimiser pour une page donnée. Le problème est qu'avec ce service, on peut récupérer une archive zip avec les images optimisées mais en perdant l'arborescence des images ce qui peut être un peu fastidieux, il est aussi fastidieux d'utiliser l'extension Firefox sur toutes les pages d'une application web pour passer en revue toutes les images et si en plus les images ne sont pas publiquement accessibles son utilisation ne sera tout simplement pas possible.
Pour pallier à cela, j'ai écrit le script shell suivant pour l'optimisation des fichiers GIF et PNG qui :
1. optimise tous les fichiers PNG avec pngcrush
2. identifie les PNG 24 bits avec identify (qu'il est peut être possible de transformer en PNG 8 bits mais cela nécessite une vérification visuelle)
3. convertit les fichiers GIF en PNG 8 bits avec convert si le fichier résultant est plus petit.

avascript is becoming increasingly popular on websites, from loading dynamic data via AJAX to adding special effects to your page.
Unfortunately, these features come at a price: you must often rely on heavy Javascript libraries that can add dozens or even hundreds of kilobytes to your page.
Users hate waiting, so here are a few techniques you can use to trim down your sites.

Web Site Optimization: 13 Simple Steps [Apache & IIS Configuration]
by camel

(via)
This tutorial takes a practical, example-based approach to implementing those rules. It's targeted towards web developers with a small budget, who are most likely using shared hosting, and working under the various restrictions that come with such a setup. Shared hosts make it harder to play with Apache configuration -- sometimes it's even impossible -- so we'll take a look at what you can do, given certain common restrictions, and assuming your host runs PHP and Apache.

Over the summer I wrote a post called 5 Ways to Speed Up Your Site that went through some basic tips for getting your site to load faster. I mentioned enabling gzip compression in WordPress and using services that remove the whitespace from your CSS, effectively “compressing” it. Now, I’ll go a bit more in-depth with a simple, yet powerful, PHP method of compressing your CSS.

Tuning LAMP systems, Part 2: Optimizing Apache and PHP
by camel
Applications using the LAMP (Linux®, Apache, MySQL, PHP/Perl) architecture are constantly being developed and deployed. But often the server administrator has little control over the application itself because it's written by someone else. This series of three articles discusses many of the server configuration items that can make or break an application's performance. This second article focuses on steps you can take to optimize Apache and PHP.
Linux, Apache, MySQL, and PHP (or Perl) form the basis of the LAMP architecture for Web applications. Many open source packages based on LAMP components are available to solve a variety of problems. As the load on an application increases, the bottlenecks in the underlying infrastructure become more apparent in the form of slow response to user requests. The previous article showed you how to tune the Linux system and covered the basics of LAMP and performance measurement. This article focuses on the Web server components, Apache and PHP.
