Css images not going throuhg Varnish

Posted by marios88 on January 12, 2014 at 2:02am

Greetings fellow Drupalers!

Despite my best effors i just noticed that some images are not served through the reverse proxy. Those rebellious image files are originating from inside CSS.

This can be easily fixed by making all those images paths absolute.

Does anyone know of a smarter way to fix this, preferably with a generic solution and end this mutiny once and for all?

Using Multisite for Performance/Scaling Reasons pt 2

Posted by brad.curnow on January 13, 2014 at 3:46am

Hi All!

I hope you had a wonderful holiday period :)

I've been thinking a lot about using multisite to reach the outcomes I desire in terms of performance/redundancy, and have firmed the concept up into the attached diagram.

Having never actually used multisite before I'm still coming to grips with some aspects, but as far as I can see there's no reason why I can't easily share nodes, users and sessions between the sites? Whilst allowing me to have certain modules turned on only for some subsites and not others?

APC + File cache + DB cache bin best practices

I was hoping maybe some one had an article or could give me some feedback on the following settings.php configuration that I'm currently using to push Drupal 7 cache bins to APC user cache and the file system via the File Cache module. Best performance numbers I got was APC for everything but that obviously has some issues with fragmentation of the smaller cached values. Some context of what I'm also using for performance
-- Display Cache https://drupal.org/project/display_cache
-- Entity cache https://drupal.org/project/entitycache

Using .module functions as hook pointers

Hi all,
I've long been frustrated by the overhead of Drupal. So, let me float this idea.

Warning about 7.26 update if you have LOTS of unpublished nodes

Posted by mikeytown2 on January 15, 2014 at 11:37pm

taxonomy_update_7011 runs out of memory and once that is fixed it can take up to 15 minutes to run.

Pantheon vs. Rackspace Managed Cloud

Posted by brad.curnow on January 16, 2014 at 4:04am

Hi All,

Wondering if anyone has any experience/opinions on Pantheon vs. Rackspace managed cloud for running high performance Drupal?

My initial thoughts are that Pantheon probably offers the superior developer experience for Drupalers, but Rackspace likely has more flexibility in terms of backend configuration at a server level for real experts (as well as being slightly cheaper?).

Unfortunately for me, Pantheon doesn't yet have servers in Australia although I'm told this is in their long term expansion plans. I can use the local CDN to serve statics at least.

Slowing D7 site..

Hi,

We have over the last couple of years built what is essentially a web based database application for our business that is accessed by our customers.. Launched in Sept 2011 and actively developed with new functionality being added since then.. We now have just under 16,000 "nodes" in the database..

The server is a Linode 1.5GB VM and runs nginx, php-fpm with APC and mysql..

Performance issues of large numbers of records in an "Unlimited" field.

Hi,

I have a requirement for a 'transaction' node. Ordinarily, this would be a node that shows payment from one referenced node to another referenced node (both using entity reference). This is then used in views to create a 'statement' of transactions listed against those referenced nodes.

There are plans floated to allow users to make simultaneous transfers, with potentially thousands of payments being made in one go. Originally the idea was to have each transaction as a separate node, but I don't think this would be wise if we now scale to this amount of transactions.

Segmentation faults

Posted by fullerja on January 22, 2014 at 8:42pm

We have a large multisite install with varnish in front of it. We have had an increase in traffic in the last week and are getting a lot of segmentation faults from one of the two web servers.

Our basic architecture is 2 varnish servers, two web servers, 2 db servers (master and slave).

Any ideas where to go to start debugging this stuff?

Plan and discuss the first Extreme Drupal Games (aka the "Golden Neckbeard" competition) for GLADCamp 2014

Posted by christefano on January 24, 2014 at 4:57am

This year's GLADCamp conference will feature the first Extreme Drupal Games! This event will run throughout the conference, beginning on Friday, March 7th and ending when winners are announced at the closing of the conference on Sunday, March 9th.

We have a sponsor who will be donating 6 identical VMs (distro and stack TBD) for us to use during the conference. I've asked that each VM have a minimum of 2 cores and 4GB of RAM, but exact specs are still being worked out. These VMs are hosted at 1 Wilshire in Downtown Los Angeles, so there will be extremely low latency.

The plan right now is for up to 6 teams to compete over the course of the weekend, tuning both the stack and the Drupal application to get the best possible performance in the allotted time. The team with the fastest Drupal site at the end of the conference will be declared the winner.

Now that we have a date and time, the question is how we're going to load test and judge the teams. What are the rules? Do we test for both anonymous and logged in users? Will contestants be permitted to rip out pieces of the stack and install completely different ones? How about the use of premade scripts? Do we allow commercial software, or go 100% free and open source?
