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.

Drupal not registering public ip after installing Varnish
Hi there,
I am going crazy about the fact that Drupal 7 does not register the public ip's from my users after installing Varnish.
I have these variables n my settings.php:
$conf['reverse_proxy'] = TRUE;
$conf['cache'] = 1;
$conf['cache_lifetime'] = 0;
$conf['page_cache_maximum_age'] = 21600;
$conf['reverse_proxy_header'] = 'HTTP_X_FORWARDED_FOR';
$conf['reverse_proxy_addresses'] = array('127.0.0.1');
$conf['omit_vary_cookie'] = TRUE;
Everywhere I look people say that this is enough, however with my site it still registers everyone is coming from 127.0.0.1

Read moreUse Tagged Cache Invalidation instead of purging specific URLs in Varnish
I stumbled across this article which describes a useful technique for doing cache invalidation. This could work nicely and have many advantages over calculating the list of URLs to invalidate on the Drupal side, as the current combination of Varnish+Expire modules does. We could hook into entity CRUD functions and add headers to the response.

Read moreHigh Volume Hosting Solutions
I maintain a news-oriented site which gets several tens of millions of page views per month. We've recently implemented an effort to include images in all of our articles. This is putting us over our bandwidth limit, which gets expensive very quickly. We are also having a minor dispute with the hosting company regarding the terms of these limits and the cost of purchasing more bandwidth in bulk.
I am recommending a CDN for hosting the images, or, failing that, another dedicated server to manage images and store backups and system monitoring data.

Anybody taken an O"Reilly course in sys admin?
Sorry if this isn't the right place (so many groups out there :)! ) but I was wondering if anyone ever took or could recommend this O"Reilly Media Course in Linux:
http://www.oreillyschool.com/certificates/sysadmin.php
I'm trying to get my sys admin chops, have some books, but thinking that maybe some structured resources would help.
Thanks and apologies if this is the wrong group; not sure where to ask this question.
Read moreVery Slow Caching, Memory Spikes
Hello, it's me again. I've been trying to monitor my site for some days now and it occured to me to re-enable Devel to check out the speed of my queries. Turns out they're the problem. Some pages load faster than others, but for places like the forum, opening a link takes FOREVER, and it's not hard to see why, on one page below these were the longest running queries in the list. There way many more cache drags like the one below.

Should I still use entitycache in Drupal 7 projects?
I have been using entitycache [1] without problems in D7. However I have not really measured lately does it really improve the performance and is there some issues? And what is the state at the moment about entitycache going to core [2] in D7 or D8?
What I am asking is:
-
Should I use entitycache in projects of any kind? (Like using APC cache ALWAYS because it does not matter is there logged in users or not.)
-
Has anyone measured the impact lately? (If it is in core it does not really make sense using it, right?)
