High Performance

This group is dedicated to solutions and approaches for high traffic, high performing Drupal sites. As such, it will deal with a lot of information around the rest of a typical Drupal "stack" -- the operating system, web server, database, and PHP tweaks that combine to support the Drupal application.

This is not a support channel or a place to post bug reports.

If you think you have found a bug, use the issue queue for the appropriate project.

Discussion of Step-by-step: Setting up Project Mercury

Posted by mgifford on February 9, 2011 at 4:41pm

I'm just experimenting with Varnish & Drupal 7 now and am getting stuck here:

http://groups.drupal.org/pantheon/mercurywiki#config-apache-varnish

I want to set this up in a environment on debian that uses both D6 & D7 sites. I'm not looking to use pressflow, but understand that this shouldn't be required with the changes in D7.

What would the minumum parameter for drupal_bootstrap needed for an ajax call to a drupal url which points to a callback that only has a return statement in it

Posted by mitchelljj on February 7, 2011 at 9:25am

Any reason why having a javascript timer fire every 2.5 second for an ajax
request to my own callback(listed below) that all it does is return the

contents of 2 _session variables would take up so much resources?

 function refreshcarttimer() {
     print($_SESSION['num_items'] . ',' .  $_SESSION['uc_price']);
     return;
 }

 /**
  * Implementation of hook_menu().
  */

 function product_type_menu() {
   $items = array();

Migrating to Drupal with lots of caching. Use Drupal 7, Pressflow 6, or Pressflow 7 ( exists?)?

Posted by DavidGen on February 6, 2011 at 7:37pm

Hello,

My company's site built in Symfony/PHP + MySQL has grown beyond my ability/resource to manage.

After the usual lots of homework, I've decided to migrate it to Drupal.

So far, much of my front-end load has been handled by a mix of Varnish cache, memcached & APC.

I see that something very similar can be handled with a Drupal module (Varnish) and the company=FourKitchen's variant/fork of Drupal, Pressflow.

I've read that Drupal 7 has now integrated a lot of what the Pressflow product offered in it's Version 6 product.

Slow performance at the top of the hour

Posted by mrwhizkid on February 5, 2011 at 5:16am

Hello everyone. I have been following this group for a while now and I hope that you can help me with a big problem. I posted this in Post Installation Issues on the forums but haven't received any response.

This has been driving me crazy but I think I finally have some solid information to work with.

My site (and actually all of the sites on my VPS) have been freezing up every day at the top of the hour from 8AM-11AM Eastern Standard Time. This does NOT correspond to any traffic spikes. This happens regardless of how much traffic I have.

Mercury (Varnish) with SSL only traffic?

Posted by cookiesunshinex on February 4, 2011 at 7:23am

Our use case for our Mercury install has suddenly changed in our architecture and it has been determined that we will use SSL only traffic.

I've been trying to read up on how to get Varnish to interact with HTTPS. It appears, to my dismay, that Varnish does not play well with SSL.

I've found this thread:
Enforcing SSL Behind AWS Load balancer
http://groups.drupal.org/node/115284

and this blog post
Setting up Pressflow and Varnish to work with HTTP and HTTPS

CDN to host Drupal files, CSS & JS. Success stories with Amazon S3?

Posted by rootdownmedia on January 31, 2011 at 5:18pm

We have a high traffic site hosted on a VPS and we are trying to offload the image, CSS and JS file requests to a CDN. We are considering using Amazon S3 and the Media Mover module to send all files to Amazon (using this approach http://www.24b6.net/2009/10/04/simple-cdn-media-mover-and-s3).

Does anyone have experience setting this up or suggestions on other approaches?

simple API added to nodejs.module for other modules to use

Posted by Anonymous on January 31, 2011 at 8:25am

I've now implemented a simple API for other modules to use Node.js functionality from Nodejs module.

Still pre-alpha code, but would love to get some more eyes on it, feedback more than welcome.

Started with this post: Add editor: XStandard (+ other desktop/browser side plug-ins?). Add info & edit to get more structured. Researching for solutions eating lesser server resources, so a desktop/browser side plug-in might be the solution. I haven't seen another like (the quality of) XStandard. But then I found many other browser/desktop editors:
