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.

applying high performance tools to vps.

This weekend I have wiped my vps clean and am starting all over. i want to put about 18 drupal sites and a couple of wordpress sites on account. i have linode 760 plan. i want to use ubuntu 10.04 lts, i think thats what its called. i am using nginx as the server. but its so confusing trying to know the right tools to add. i believe i can add memcache on the nginx server, but how do i add varnish and apc, or do i need to add all three of those? the documents and different pages i am finding totally confusing. do i use modules to install these tools or do i do i install them at the server?

Memcache and empty blocks

Hi

We had been running a site for some time with apc+memcache+cacherouter with no problems, when we suddenly we started to get blank pages (I say suddenly because we couldn't find out exactly what was going on).

Well, not blank pages, but more like blank blocks. In the end it looked like memcache was not able to return what it was supposed to and the pages were being drawn pretty badly. Flushing all the caches fixed the issue, but only for a couple of minutes.

Moved mercury to larger Amazon image but cant get memcache working correctly

I've been running mercury for a year on a small amazon instance. Performance wasnt great so I decided today to move it to a large instance, which is quite a step up.

I started with a fresh Ubuntu 10.04 and installed Apache, Varnish, Memcache, etc. I moved my database over and pointed the IP at the new instance. The site shows up and Varnish is working, but no matter what url I goto it shows me the main page of my website.

About caching for anonymous users

I've done quite a bit of research on Drupal performance, caching, have got memcache, APC, pressflow and so on all set up but have a problem.

I have written a custom module that works similar (I would imagine) to how the flag module would (I imagine) work for logged out users, i.e. store flagging actions to the session then sync those to the user account on login or registration. Now imagine being able to see how many items you had flagged somewhere in the header, these counts are pulled from the session. For logged in users, the counts are pulled from the DB / memcache.

Using Project Mercury - do not see Cache Router config in settings.php

I'm getting ready to launch a site based on Pantheon's Project Mercury, but I'm not seeing evidence that the site is using things like APC correctly.

Reading other places online, it seems that when using Memcache you have to tell Drupal to use it in settings.php with something like:

$conf['cache_inc'] = './sites/all/modules/contrib/cacherouter/cacherouter.inc';
$conf['cacherouter'] = array(
'default' => array(
'engine' => 'db',
'servers' => array(),
'shared' => TRUE,
'prefix' => '',
'path' => 'sites/default/files/filecache',

Defining the Drupal 8 performance gate

(From webchick:)

Hi there, performance team! :)

Back at DrupalCon Chicago, Dries outlined a strategy for Drupal 8 involving a series of "gates" that would help ensure core code quality in a number of different categories: Documentation, Performance, Accessibility, Usability, and Testing. The purpose of gates is to define essentially a set of "checkboxes" which outline the most important aspects to each category, and does so in a way that is both not overwhelming to core developers (list of hoops to jump through is kept as small as possible) and also creates very little additional burden on the team in question (contains sample links to documentation/resources so developers/reviewers can help themselves).

Since we have already traditionally had requirements around documentation, it made sense to start there. Jennifer Hodgdon and some other folks from the documentation team have put together the Documentation gate, which is available at http://drupal.org/node/1203498. What we need is a similar table for each of the other gate areas. And that's where you come in! :D
