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.

Multi process Drupal

Posted by mikeytown2 on January 14, 2011 at 5:41am

I've been thinking about a way to make Drupal's page rendering utilize multiple cores of the server for a single request. Vanilla PHP can be used to create as many child processes as one desires, so the question is how do they communicate and where's a good place in the code to make it MT. My gut says spiting up by region. That would require modifications to these functions most likely.

Scalability of a forum with node access

Posted by jcisio on January 11, 2011 at 1:26pm

Hello,

I'm looking for a forum solution for a Drupal site. This forum must support moderating. Is there any lightweight solution, or is the forum access module scalable? Last year I had problem with a node access module. Is it correct that Forum Access sustains the same issue?

Do you know any big forum (a few dozens of thousands of nodes or more) that uses the Drupal forum?

Thanks.

Query cache Issues, Performance Issues and Version of MYSQL

Posted by gdtechindia on January 11, 2011 at 10:14am

Hi Everyone.

I was reading on several forums that using MYSQL 5.5 will be a good option as it improves the performance compared to my current version 5.0.77.

I guess we are able to run things, only because we are using boost to completely cache the server.

I have listed some of the status variables from our website's drupal admin below. Some of them, made me think that something is wrong.

What should we do in order to correct the issues.

imageinfo_cache module

Posted by mikeytown2 on January 7, 2011 at 2:00am

Looked at cachegrind output and image_get_info was taking a lot of time; called from theme_imagecache. My files dir is a S3 mount thus its a little bit slower. I did some local testing and if the file is local a cache_get is slower. But if the file is not local then cache_get is way faster.

I've attached a simple module that works; anyone find this useful? It works by overriding theme_imagecache.

Memcached tuning: "object too large for cache"

Posted by mshmsh5000 on January 5, 2011 at 4:31pm

We have a Pressflow 6 app with Cache Router routing to multiple memcache bins. The bins have plenty of memory allocated, but other than that are running with default options.

In local testing, I've found that some basic cache-setting fails because of object size. Examples:

&lt;20 set cache_views-views_data%3Aen 1 0 2721377
&gt;20 SERVER_ERROR object too large for cache

&lt;20 set cache_menu-links%3Aadmin_menu%3Atree-data%3A788912d6fd7adf98c8c86af7c57d00fe 1 0 1670355
&gt;20 SERVER_ERROR object too large for cache

Managing content as nodes in a separate database

Posted by lsiden on January 4, 2011 at 5:50am

I am managing a site with over 19 million business listings. Cloning a database this size is daunting and time-consuming. Most of this data is static, but there are some definite advantages to managing it as nodes. In a perfect world, I'd like to be able to move these 19M nodes to a separate database so that I could easily clone the rest of it for development and testing, but I can't think of any way to do that that will allow me to keep working with the data through the Drupal Node Module with its incumbent advantages.
