performance

Varnish is a very fast HTTP cache server, which is to your Drupal what a big rotation press is to a newspapers DTP system.

Want to deliver thousands of pages per second with very low responsetime ? Varnish is your tool for that.

And Facebooks, and BBCs, and SlashDots, and ...

In this talk the author of Varnish will show off his warez, lift the hood and make you think about servers and content delivery in an entirely new way.

Varnish is a reverse proxy cache. It accelerate your web site by caching responses from your web server and thereby offloading Drupal. Varnish is a modern solution outperforming its competing products by as much as twenty times. That is the reason for its increasing popularity as web accelerator.

Audience

This session is for anyone who is not afraid to manage Linux servers, but who has not yet looked into Varnish.

What you will learn

In this session you will learn:

• What Varnish is.
• When to use Varnish.

Honestly speaking, Drupal is a big out of the box system. It carries a vast amount of queries per page load, and uses quite a few MB for its PHP memory size.

Having the experience on more than 250 developed projects we pledge that Drupal performance can be vastly improved according to your website's goals. Indeed, using the right tools we always achieve the results of the Powerful CMS + Amazing Performance.

One power-feature of Drupal is flexibility. You can take what's already made by others and create your "own" version of the system.

Having the experience on more than 250 developed projects and always exceeding our clients' highest expectations, we have identified absolutely-must-have modules fitted for different types of sites, and to benefit your customer with the full extent of this great CMS.

Also, our in-house research has shown there are many small enhancements that can make a big difference.

This will not be a deep technical talk about how to make your site fast, nor will it be a marketing piece. I will take an in-depth look at the technologies that help Drupal perform and scale to the masses.

I will point you to the technologies and best practices that have been going on lately in the Drupal community, give you a rundown of where we came from and show you where we are going and how to get involved. I would suggest that you have at least a basic understanding of LAMP stack and basic Drupal tuning to get the most from this talk.

Apache SOLR is an emerging new technology to support all major Drupal site's powerful search. But it's not just searching that it does.

With Apache SOLR your site can do a lot more than just faceted searching fast and easy. You can use SOLR to power your Views, Panels, Übercart and a lot of other stuff, with some new contrib modules.

Drupal contains many layers of abstraction. If you're tasked with making a Drupal application perform well, it can be daunting trying to locate all of the possible bottlenecks. Query loggers and print statements are great, but sometimes we need something better, faster and stronger.

Varnish Cache is a web accelerator, also known as a caching reverse proxy or a HTTP accelerator.

This talk focuses on what Varnish does, how Varnish achieves its performance levels, its architecture and future development. Experiences from applying Varnish to varnish-cache.org (a trac site) and varnish-software.com (Drupal 6 Pressflow) is presented.
