Bitnami Blog: Performance enhacements for Apache and PHP

פורסם ב: by

Performance enhancements for Apache and PHP

In addition to updating and expanding the #Bitnami Library, we are continuously looking for ways to improve our existing Bitnami stacks. In this latest round of updates, we focused on improving the performance of our Bitnami Stacks in limited resource systems such as #Amazon #EC2 micro instances, which have 1 virtual CPU and 613 MB of RAM, and Microsoft Azure extra-small virtual machines, that ship 1 CPU core and 768 MB of RAM.

We have now configured our Virtual Machines and Cloud Images to use the #Apache Event MPM and #PHP-FPM, resulting in reduced memory usage and an increase in the number of simultaneous requests that they can handle.

 

What is the Apache event MPM?

Apache supports three different Multi-Processing Modules (MPMs) that are responsible for binding to network ports on the machine, accepting requests and dispatching children to handle the requests.
