Yslow score: Add Expires headers - Configure entity tags (ETags) - Make fewer HTTP requests
I am trying to optimize my sites

There are 41 static components without a far-future expiration date.

There are 40 components with misconfigured ETags
Is this important? How to improve?

Pressflow Question
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.

backups and disk image allocation
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?

Pressflow - PHP Notices
Currently fixing various notices and I find this query to be very useful in phpmyadmin. Be sure to have "Full Texts" selected under options.
SELECT
COUNT(*) AS count,
watchdog.*
FROM watchdog AS watchdog
WHERE type = 'php'
#AND variables NOT LIKE "%SQL%"
GROUP BY variables
ORDER BY
count DESC,
wid ASCThis is what I use on the dev box in settings.php; makes errors very verbose and enables dblog if it is disabled.
<?php
// Show Errors in output
ini_set('display_errors', '1');
// Report all php errors.

High performance Drupal advice (game server)
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..

Memcache as a service @ AWS
Very interesting. Memcache as a service.
http://aws.amazon.com/about-aws/whats-new/2011/08/22/announcing-amazon-e...
If anyone happens to kick the tires on this with Drupal I'd be interested in feedback on how it works. I don't have time at the moment to take it for a test drive but it looks quite interesting.
Read moreBenchmarking Views with mysql query cache on by default
I'm trying to benchmark a View on a MySQL server shared by a number of other developers, so I don't have the luxury of turning off query_cache_type since as far as I can tell, it's server wide and not restricted to per database.
I believe there's a way to turn it off per session, is there either a good way or otherwise, that I can set my particular development branch to operate with query_cache_type off.
Alternatively, a way to push SQL_NO_CACHE into Views either globally or per View would be fine.
Thanks for any advice :)
