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.

Advice on best way to serve Audio Files (MP3 etc) - Linux Box

Posted by spessex on April 4, 2013 at 6:21pm

I just wanted to know if anyone had any advice or experience with using small/short audio files in their websites?

I'm intending on placing the odd audio clip into a survey to test advertising effectiveness. The audio clip will be short, around 30 seconds and the survey might be hit by a 1000 users over the period (with the possibility of up to 300 users accessing the survey - and the resulting audio file - at anyone time (depending on when they hit the server).

Comparison of shared files directory solutions

If you want to have multiple webservers for a Drupal site you need to keep your code and files directory in sync across all the webservers.

For synchronizing the code solutions like capistrano, drush deploy, fabric, phing are all good solutions. Sharing the code using a network file system doesn't usually perform well because the files are re-read (or at least stat'd) during page load which is slow.

High Performance expectations

Hi Guys

I am looking for a system where I can cluster MySQL. I saw an article which guided me to custom Drupal schema for NDBCluster engine for MySQL clustering, Btw. I am using Drupal 7 with Varnish, memcache etc.

And I also saw another solution for clustering MySQL using Galera Cluster

(MariaDB and Percona also uses this for Clustering) Scaling Drupal stack with Galera)

The reason why I need a cluster is because my fields are over 8 kilobytes There will be a minimum of 15.000 Users visiting the site at the same time.

Anyone have a copy of pressflow 5?

RAM Recommendations/Help

Posted by Ony on March 27, 2013 at 7:52pm

Hello everyone,

I've spent the past few months figuring out Drupal and I've come a long way I think. I recently set up a site with about roughly 70 modules. It's supposed to be very interactive and I hope to get a lot of logged in users, with groups, forums, etc. By the time I tested it on a live server, I realized the site was actually a bit slow. Along with that I was getting constant complaints from my host. I moved it to a VPS with about 550MB Ram, and though I rarely seem to hit the limit, there are brief (like a few minutes) 'spikes', said spikes result in a warning from my host, and occasionally what looks like a server restart that cripples my site for about ten minutes.

PHP 5.5 with ZendOpcache in core is here (almost). What changes does this require in the HP stack where APC used to be?

Posted by drupsup on March 25, 2013 at 10:51pm

PHP 5.5 Beta-1 has been released.

Zend Opcache has been opensourced, and is now included in PHP as part of core.

APC, otoh, seems to have languished. Development has slowed, and, atm, there's no version/tree that's 5.5.x compatible. APC 3.1.14 which was focused on PHP 5.4+ compat has been pulled due to memory issues; 3.1.13 is the most current stable release.

Reading the lists and the tea-leaves, it appears that most, if not all, resources will henceforth be applied to development/maintenance of Zend Opcache.

Hi everyone,

Performance Profiling Recommendations

Posted by galaxiecruzin on March 21, 2013 at 8:14pm

First off, thanks in advance for any comments/recommendations.

Over the past few months I have been working on performance tuning a D7 site that includes Drupal commerce. Using NewRelic, I was able to determine that menu_tree_check_access() was being called on every menu item with the Taxonomy Menu Block. I quickly replaced the menu block with Views that does the same thing as the menu block did, except much faster...

Building a Drupal 7 Optimized my.conf File

This is an attempt to hard code some of the many best practices that are brought up in various posts scattered on the internet. Please feel free to edit, particularly adding to the documentation of the configuration. My assumptions are we're working with at least 8GB of RAM, 2*Dual Core CPUs, 64bit operating system, EXT3 file system & Debian.

The MySQL database server configuration file.

You can copy this to one of:

- "/etc/mysql/my.cnf" to set global options,

- "~/.my.cnf" to set user-specific options.

"Caching mode" stuck at "Normal" on Pressflow website with Varnish 3

Posted by yngens on March 21, 2013 at 11:21am

Hi All,

I am hitting the same strange problem as was described on http://drupal.org/node/1613386 for Barracuda project. The difference is that I am not using Barracuda, but Pressflow on CentOS 6.4 server with Varnish installed and running.

I tried to play with various cache options, clearing it, turning it off, but it never selects Disabled, Aggressive or External. It's just stuck on Normal (recommended for production sites, no side effects). Could anyone suggest how can I set it to External?

Thanks.
