Some installations of Apache will have been compiled to work with either Prefork or Worker MPM, but most by default are compiled only to work with Prefork. Changing to Worker MPM may allow your server to handle much higher traffic, more user sessions, with less RAM use. Your site or server will not scale well if it is running Prefork MPM. Worker is a bit more difficult to set up properly, and has some restrictions regarding functionality of PHP … 17, 2, 5, 0 and 48.99
Tuning Apache and MySQL for Best Performance in a Shared Virtual Hosting Environment
ld. Wait 1 hour, and run mysqltuner to see if there are any recommended changes. Mysqltuner will show you the maximum memory which will be used by mysql. You should adjust config variables to take up no more than 60% of total RAM. Wait 24-48 hours and run mysqltuner again. Example mysqltuner results: ——– Storage Engine Statistics ——————————————- [--] Status: -Archive -BDB -Federated +InnoDB -ISAM -NDBCluster [--] … 8, 1, 0, 0 and 16.24
How to Configure APC Cache on Virtual Servers with PHP running under FCGId
APC INFO Monitor My Virtualmin CentOS 5.6 Virtual Private Server runs several virtual domains with PHP under FCGId using APC for opcode caching: Joomla, PHPbb, WordPress, etc . APC is somewhat challenging to configure properly with fcgid-enabled virtual domains, but it is quite helpful to optimize system resources and prevent traffic surges on one site from affecting overall server performance. Joomla and PHPbb have code that is pre-optimized wi… 8, 0, 1, 0 and 15.19
Apache and MySql Performance Tuning for High Traffic Website
errals provide the revenue stream. SoccerNews.com website I was contacted by the publisher after responding to a plea for assistance in a WordPress.org support forum. Though the site was running on a dedicated server with 8GB RAM, it was crashing frequently under load. The developer tried implementing APC Alternative PHP Cache and W3 Total Cache, but these measures turned out to be incompatible with some of the custom PHP code and the software ar… 4, 1, 2, 0 and 13.63
Load Balancing Virtualmin WordPress Hosting Server with Varnish on AWS
I am creating a true load balancer topography for a WordPress hosting server, if it needs to scale up beyond what the current system can handle. Scaling Levels The current system is the “admin” path shown in the diagram, with no CDN or Load Balancing. It will handle a lot of traffic, but it is somewhat vulnerable to failure and overload. A simple and inexpensive extension of this system is to add CloudFront CDN, the “beta users… 6, 0, 0, 0 and 8.91
WordPress with W3 Total Cache on Nginx with APC (Virtualmin)
Virtualmin now includes support for Nginx web server. I deploy many WordPress sites with W3 Total Cache and APC Alternative PHP Cache, so I was very interested to see how Nginx performance compares to Apache for WordPress, and whether APC and W3TC would play nice with Nginx. I prefer to install WordPress in public_html/wordpress for ease of development, compatibility with other scripts, etc. Accordingly, the suggested configuration is for WordPr… 6, 0, 0, 0 and 8.91

Punk Rock Music Community
Punktastic.com is a community powered site that covers punk music in Britain, but is poised to go worldwide. They cover punk and hardcore shows and festivals, and provide album reviews, video interviews and more. With a growing audience and user base, Punktastic needed a more reliable and robust web server, so they made the move to a dedicated CentOS 5 series web server with 3GB RAM. While this is a relatively low-end box, it has plenty of horse… 2, 0, 0, 0 and 3.66
APC Cache Considerations for Virtual Hosting Environments
APC cache does not work well in a virtual hosting environment unless PHP is running as FCGID, and every individual virtual host has a unique PHP.ini and a unique fcgiwrapper. This is not the case with many virtual hosting environments because the memory and CPU requirements are too great. I suggest using Virtualmin for a shared hosting environment with APC cache, because it does allow to set php.ini and fcgiwrapper for every individual virtual h… 1, 0, 1, 0 and 2.6
