Sharing Files directory (NFS) on load balanced IIS

Posted by dipen chaudhary on October 23, 2010 at 12:10pm

Hi,

One of my clients who have constraints to use windows in production with IIS 6.0 have the following architecture:
1 hardware load balancer, 2 web servers and 1 dedicated mysql servers. It now has the classic issue in which the files directory on web01 and web02 needs to be either shared on a network file system or be in sync with each other. More
robust solutions are to use data cloud or a distributed file system, the last 2 options are out of question and currently we are looking at the 2 classic solutions.

Improving authenticated user performance

Posted by ghankstef on October 25, 2010 at 5:46pm

The basic question is how to optimize performance for authenticated
users on site with heavy forum traffic that requires membership. In
general performance is adequate but there are spikes of heavy traffic.
Site is for a band. On occasion the band member
will tweet and link to the site and hundreds of users will log in to
see what is going on. Thus the traffic spike.

Metrics: Highest traffic in the last 60 days was 3667 visitors in a
24 hour period. Of this 3317 users were authenticated users with
accounts. This is according to Google Analytics.

List of community sites running Drupal (and are fast)

Posted by okokokok on October 30, 2010 at 4:47pm

I'm curious to know. Apart from drupal.org and g.d.o, which community websites are running Drupal and are reasonably fast?

I'll be happy to start a wiki page with a list if there is no list like this yet.

High Performance Sessions at DrupalCon Chicago

Posted by schnitzel on November 6, 2010 at 9:59am

This year at the DrupalCon Copenhagen we had a lot of different performance related Sessions. I watched mostly all of them and in the end I need to tell, that they are no big differences between them.

Now the Session Proposal for DrupalCon Chicago 2011 is open and I thought, why the different speakers can't organize before and make only two or three performance sessions, but them really great!

I'm thinking about a first sessions for beginners in which High Performance for Drupal is first explained, with some easy stuff.

Conditional Caching for anonymous users

Posted by shadysamir on November 9, 2010 at 1:04pm

We are building a website where anonymous users need to be validated using their IP address and hence providing them with different content and page builds based on their identity detected by their current IP. We have full control of the IP allocation and are able to determine users based on that. We wish that users do not need to register an account with the website to access this content. Boost is being used for caching.

Any method for clearing unused values from the 'variable' table?

Posted by vacilando on November 9, 2010 at 11:33pm

After a Drupal install has been used a while, the table 'variable' overflows with values set by various disabled modules or obsolete functions which do need clearing because variable_init() (bootstrap.inc) does that unfortunate step of caching all of the table, which then often causes sites to crash due to lack of PHP memory.

Module developers may choose to use functions alternative to variable_set() and variable_get() provided by http://drupal.org/project/queryable_variables but that does not solve the pollution in all the existing 'variable' tables.

Cookies and analytics

Posted by seanfitzpatrick on November 11, 2010 at 10:33pm

Hi there,

This may be the wrong place for this discussion, but I members of this group will have expertise far beyond mine.

I'm running the Pantheon stack on the recommendation of some very helpful consultants, but I have some gaps in understanding on how the whole thing works. I've never quite understood, for example, why the number of "anonymous" users in the corner of the Admin Menu typically floats around 12-14, when with the Merury/Pressflow stuff turned off, the number is always higher.

How to do IE conditional JS from a module?

Posted by realityloop on November 15, 2010 at 11:47pm

I'm trying to build a webform plugin that requires some additional JS included for IE browsers based on the version, the JS I'll need to output on webforms is as follows:

<!--[if gte IE 7]><script type="text/javascript" src="excanvas-r71.min.js"></script><![endif]-->
<!--[if IE 6]><script type="text/javascript" src="excanvas-r3.min.js"></script><![endif]-->

I've been trying to get drupal_add_js to work, I'm still learning jQuery and am not sure that it is the best way to check for browser or having a lot of luck getting it to work.

Here is where I'm at:
