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.
If you need support, see http://drupal.org/support for options.
We are in the process of getting ready to release a game in the next few months, most of all the back-end is handled by drupal and some custom plugins, but we are now looking to move towards the cloud and making sure drupal and the db can handle the traffic.
I have started down the road of googling all over the and of course ran into project mercury / panthon / press flow etc..Read more
Interested in Pressflow, APC, Varnish and memcache? Want to jump from shared or "grid" hosting to VPS or dedicated hosting but aren't sure what to do? Do you just want to get more out of what you currently have and take your Drupal site to the next level?

Currently fixing various notices and I find this query to be very useful in phpmyadmin. Be sure to have "Full Texts" selected under options.
COUNT(*) AS count,
FROM watchdog AS watchdog
WHERE type = 'php'
#AND variables NOT LIKE "%SQL%"
GROUP BY variables
This is what I use on the dev box in settings.php; makes errors very verbose and enables dblog if it is disabled.
// Show Errors in output
// Report all php errors.
I hope this is the right place to ask this question. I decided to pay 9 dollars a month to linode for image backup of my vps. right now, its not so important because i keep having to rebuild my disk image and i dont need to save anything. right now, i leave 14% of my vps for backups. but am i supposed to leave 50% of my disk image free for backups? do most people leave half or more of their vps foe backups?
Hi, I have drupal 6 site that has spikes in traffic usually on the weekends. We also use boost to increase performance. Not to long ago we started to have a problem where the sites main navigation started to disappear, sporadically. Now we use a bit of custom code to create and manipulate the main menu (primary-links) so it is easier for our users to change the menu as needed. So our menu gets created by sending the return data from menu_tree_all_data() for the primary links menu.Read more
I am trying to optimize my sites
- D6 multisites one codebase, separate databases
- APC, cacherouter, Authcache, Boost
Yslow rates F for the followings
Grade F on Make fewer HTTP requests
This page has 3 external stylesheets. Try combining them into one.
This page has 22 external background images. Try combining them with CSS sprites.
Grade F on Add Expires headers
There are 41 static components without a far-future expiration date.
Grade F on Configure entity tags (ETags)
There are 40 components with misconfigured ETags
Is this important? How to improve?
Has anyone ran Drupal with the Transaction Isolation Level set to READ UNCOMMITTED? REPEATABLE READ is the default setting, but I think for 99% of the sites out there using dirty reads seems like it would be very helpful.
How to set this in my.conf or via SQL command:
transaction-isolation = READ-UNCOMMITTED

This weekend I have wiped my vps clean and am starting all over. i want to put about 18 drupal sites and a couple of wordpress sites on account. i have linode 760 plan. i want to use ubuntu 10.04 lts, i think thats what its called. i am using nginx as the server. but its so confusing trying to know the right tools to add. i believe i can add memcache on the nginx server, but how do i add varnish and apc, or do i need to add all three of those? the documents and different pages i am finding totally confusing. do i use modules to install these tools or do i do i install them at the server?Read more
