Pressflow / Varnish - Removed Google Analytics cookies still stopping response header 'age'?
Currently using Drupal 6 / Pressflow on Apache with Google Analytics installed. We have Varnish 2.1.5 running on port 80 in front of Apache.
In the attached Varnish VCL (based on Lullabot's example - http://www.lullabot.com/articles/varnish-multiple-web-servers-drupal), I have (probably redundant) regex filtering Google Analytics cookies, as well as a general 'remove all cookies except sessions' rule in sub vcl_recv.
Read moreDrupal 7 Site Performance and Advice
Hi,
I am involved in a Drupal 7 site, I am note a Drupal Developer but I am IT savvy.
Anyway the site was recently moved onto a dedicated server due to heavy usage at certain periods. The site is young but growing fast, circa 1k users and during the heavy periods at least 70 users logged in...maybe lots more - shared hosting was no longer a suitable option. As it was an emergency we were recommended a server and migrated to a dedicated server: Quad Core CPU, 32GB RAM, 300GB and Plesk (for alerts) - fastcgi is in use but I am not sure what else as I don't have access :( .
Read moreVarnish with Apache or NginX & php-fpm
I "think" I managed to get php-fpm working reasonably well with my Centos apache server. Running memcached and apc with 2GB of RAM on a VPS.
I am now planning to tackle Varnish. My question is should I be running Nginx for the varnish "static" anon content and/or the entire Drupal 7 site?
Looking around the web, there appear to be many examples of deploying Varnish with Nginx, not so much with apache?

Does the mongoDB integration really work in real life ?
Just in the process of planning a web project with a lot of fields the mongoDB integration came back to my attention.
When people speak about the integration they tend to point to a massive performance boost when writing and reading. But what is the real world factor here ?
Even more important is the data access. I know there is the EntityFieldQuery which give a way to integrate with Views. But is this production proofed; how does this work in a real world application ?
Read moreBlock caching and access modules
Previously I had a serious performance issue on my website.
The reason is that I have a big menu with 130+ menu links.
Content access module was breaking the block caching, and the website page loading was 4 times slower. It was a real head banging until I found what causes that issue.
I've removed the content access module and wrote a custom code for block caching.
Right now I've added a Advanced forum on the same website with many features.
Unfortunately I have to use Forum Access module, because real forum is nothing without permissions.
IRC Channel: #drupal-performance
Hi High-Performance and Benchmarking-Drupal,
I thought it would be great to have a dedicated channel for high-performance discussions.
If there is already another channel, please point me to it, but if not lets all join #drupal-performance on FreeNode to discuss all performance related matters and especially also D8 performance.
Once we have enough people there we can even request a bot :).
Thanks,
Fabian
Read moreHigh latency with loading images
Hi there, have a website which seems to have very high latency with rendering images.
There is nothing special going on here, images are fields on content. Rendered using no Image style, from the same server, from the default path on the drive, anonymous users, performance caching is set to enabled, cache cleared, nothing in the logs, TOP from the prompt shows tons of free memory but I am getting lags of 12second latency on loading image assets even though the rest of the page loads fine.
Phpini shows 140MB of memory set.
What are other possible causes for this?
Thanks,
Seb.

About Extreme Drupal
Formerly known as the High Performance Drupal Meetup, this event covers Drupal scalability, performance and benchmarking as well as devops, deployment, infrastructure, high performance hosting, monitoring and highly repeatable processes.
All are welcome but this is not a meetup for beginners.

Read moreIncreased response time after migrating PHP5.3 to PHP5.5
We have just completed an update of PHP on our servers. We went from 5.3 to 5.5. We have a pretty big site with lots of nodes, blocks, views, modules and users. Everything was working "ok" (there are some area's we know we can improve) but now with php 5.5 our response time has almost tripled on our main Drupal 7 instalation. On other Drupal 7 instalation the response times went down.
Digging more in to this we found that there were 3 hooks that really caused this increase:
- init
- entity_property_info
- views_data
