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.

Authenticated traffic scale options

I'm wondering if people have any recommendations on scaling authenticated traffic sites?

Context: We've got about 2,500 users, of whom, 50-100 are on at any one time throughout the day. Right now their interactions are on largely static pages so we've gotten away with display_cache / entitycache / APC / Advagg for cache bin optimization so we can deliver pages pretty quickly.

Cache optimisation for admin menu


Wanted to post this here as Admin Menu is a great module! It allows your to provide quick and easy navigation to the most used parts of your Drupal administration experience. It provides cache clearing and searching and an array of other nice to haves that don't ship with the default Drupal administration menu. However due to the way that the menu needs to be kept up-to-date this module does not scale very well and can be a prime contributor to slow cache rebuilds and memory issues for larger Drupal sites.

Memory profiling in hooks


Wanted to post this to this group as well about my investigation into the memory used by drupal's various hooks in a site that I'm developing. As a result of the monitoring I was able to find ways to either eliminate or mitigate many RAM zapping functions and hooks as well as finding ways to mitigate some other functions (like optimizing the core book module's navigation rendering capabilities).

I used this dropbucket of functions to do the profiling w/ devel to dpm the output dropbucket.org/node/2036

DOM hacks for speeding up page download times

ATTACHED: comparison of download waterfall before and after applying these hacks to my page.

Hi Team,

I wanted to share with you some techniques I've discovered over the last couple of days that seem to have a noticeable impact on download times. These are especially applicable to pages with large CSS files on first load, as once things get cached it doesn't make much difference.

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.

Read more here: http://zephir-lang.com/

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.
