High Performance

This group is dedicated to solutions and approaches for high traffic, high performing Drupal sites. As such, it will deal with a lot of information around the rest of a typical Drupal "stack" -- the operating system, web server, database, and PHP tweaks that combine to support the Drupal application.

This is not a support channel or a place to post bug reports.

If you think you have found a bug, use the issue queue for the appropriate project.

If you need support, see http://drupal.org/support for options.

Tried Zephir + Drupal

Hi all,

So I've been trying Phalcon the last few days and also started making my own extensions today using Zephir. Zephir is basically a high-level programming language that makes compiled PHP extensions. So it's supposed to be like the best of two worlds - compiled performance and easy development.

I started using it today and since I had nothing better to compare it with I started porting some of the functions found in Drupals common.inc, just for learning. And it is very easy to use.

Master Master database replication - Key issues

Hi all.

We have a setup that requires master master replication for both HA and load balancing. We have an identical stack in two cities, seperated by a 1gbit WAN link. WebServer (WS) / Database (DB) / Search (Solr) servers in one city, and the same at the other.

Currently both WebServers are pointing to the same database in City 1. The reason being we cannot get a stable master master replication setup working.
