DrupalMad Julio 2010

I think that it would be great to attend this presentation.

I give +1

I'll try to attend the conference.

So apologies, the presentation didn't go as planed :)

The basic idea was: Hardware is cheaper the programer time, so if your spending programmer time to improve performance, it better be making BIG improvements.

The key points where as follows:
Pages served was tested on a clean install with a few hundred nodes generated by devel, it was tested as an anonymous users hitting /node.

1. Drupal with all caching turned off is slow. On the test sever i used, could server about 1 page per second.
2. Drupal with the 'normal' drupal caching enabled can server about 4 pages per second.
3. Authcache module - http://drupal.org/project/authcache
   Designed to allow authenticated users to be served partially cached pages, with the rest being loaded via AJAX, but can also be used to serve full cached pages to non authenticated users.
4. Cache router - http://drupal.org/project/cacherouter
   Allows you to use several different caching methods to speed up cache tables as well as Authcache.
5. Drupal + Authcache + Cache router using the DB as its store could serve about 8 pages per second
6. APC - http://php.net/manual/en/book.apc.php / http://blog.janjonas.net/2010-01-04/ubuntu-setup-apc-for-php5-and-apache2
   APC is a opcode cache and can also be used by cacherouter as a caching system. It speeds up php and reduces its memory usage. Its MAGIC and if your not using it, you really should be.
7. Drupal + APC can serve 12 pages per second
8. Drupal + APC + Authcache + Cache router using APC can serve 17 pages per second

Benchmarking can be done a few ways, one very good way is using JMeter, prebuilt test scripts can be found here : http://groups.drupal.org/node/53963

Dont be scared of authcache and cache router, they are VERY VERY easy to set up and give you a nice speed boost especially if your already running APC.

If your serious about making your site fast, you might want to read up at : http://groups.drupal.org/high-performance and look into some of the other steps you can take. There is a whole world of performance turning out there.

Esteinar, la referencia más grande junto al Medialab es el Caixaforum. Seguro que lo conoce mucha gente y es una localización por la que preguntar para pedir indicaciones.
El Medialab está en una placita que hay frente al Caixaform (ojo, no la del elefante), pero está en los bajos de la plaza. Se entra siguiendo la rampa, la puerta de metal de la esquina del fondo. En ocasiones hay un grupo de personas sin techo frente al Medialab y eso puede desorientar.

There is free internet acces for everyone.
We have to ask about the connector.
