MySQL memory usage

Recently i have briefed few possibilities to increase MySQL response time and overall performance, so let’s talk how we can tweak configuration file of MySQL to bridge the gap between blazingly fast CPUs and comparatively slow disks, certainly “the memory”. By adjusting how much memory MySQL uses, you can often realize significant performance improvements, but before that we need to understand how MySQL uses memory. As MySQL is extensively tested for any memory leakage, we can focus our concern to any miss configuration and hence miss utilization of memory. MySQL provides different default configuration file that you can configure further, according to your server hardware and traffic.

Optimizing MySQL performance

Performance of any web application depends on several aspects, some times web server alone can cause a lot of performance diminution if not configured properly but the major concern for any web application performance degradation are the database. Lots of applications are constantly being developed and deployed using the LAMP (Linux, Apache, MySQL, PHP) architecture. Certainly the server administrator has little control over the application itself because it’s written by someone else but they still play a major role for any web application performance. Today i’m going to discuss another major performance issue, MySQL memory bottleneck.

Let’s start with estimating your web site response time, using curl
curl -o /dev/null -s -w %{time_connect}:%{time_starttransfer}:%{time_total} http://www.google.com/

Configure Apache php and MySQL

So here i’m to share, how i use to configure Apache php and MySQL on Fedora’s system, this configuration works fine with all fedora versions above and with core 3. In Tekriti we develop social networking sites (more about me and tekriti) that uses some feature configured with apache and php which are not compiled by default, for example with apache we need mod_rewrite and mod_proxy enabled and with php, soap and gd.
