Thanks for eNovance to send me there, I’m really happy !
Yesterday a colleague (Dimitri) tested a tool on this blog. He informed me that Varnish was disabled and PageSpeed may be the cause as this is the last modification I’ve made on the server.
After verification he was totally right ! By default, PageSpeed disable cache by serving HTML files with:
Cache-Control: no-cache, max-age=0 After reading the PageSpeed documentation on that topic, it is clear: PageSpeed needs to know how to purge the cache as it rewrites a lot of elements and it has the control instead of the application.
It’s not really common, but here is a tutorial I’ve made to analyze of a crash dump on Windows. I’ve only talked about how to setup the tools and how to use them but do not talk about the analyze itself. May be in another post if I have enough time.
Once again, I hope it could help some of you
Following a previous post, I’ve enabled PageSpeed on both wiki and blog deimos.fr.
What I can say is, it’s very important to take the time to test every optimizations you want to add. I experienced for example issues on silly things like :
# Optimize browser rendering pagespeed EnableFilters lazyload_images; Some images weren’t shown if you didn’t refresh once again your page browser. I only had this problem on the blog and not the wiki.
Don’t miss the Ceph Meetup on Monday ! You will be aware of the new features in Firefly (like tiering or erasure coding) ! And this is the first long time support release !!!

I’ve first heard of Page Speed last year for Apache. I was really waiting a stable version for Nginx and it’s now done. A few days ago, Nicolargo made a post regarding it and that’s what motivated me to go ahead on Page Speed.
PageSpeed speeds up your site and reduces page load time. This open-source webserver module automatically applies web performance best practices to pages and associated assets (CSS, JavaScript, images) without requiring that you modify your existing content or workflow.
I discovered Dotdeb a few months ago and decided to make a quick documentation to install the repository. But before, here is the official explaination of what is the repository made for :
Dotdeb is a repository containing packages to turn your Debian boxes into powerful, stable and up-to-date LAMP servers :
Nginx PHP 5.4 and 5.3, useful PHP extensions : APC, imagick, Pinba, xcache, Xdebug, XHprof… MySQL 5.
