Nginx reverse proxy , Apache Drupal and Boost

Posted by jayatdrupal on March 29, 2011 at 3:58pm

A nice way to add performance to your drupal site is by adding Nginx in front of your web server to act as a reverse proxy. I have summarized my configuration which puts Nginx in front of an existing Apache / drupal site. Not only can it serve images and other static files, but I have made the tweaks to the configuration file to serve up the boost cached files directly from the Nginx front end.

My testing shows it to be very, very quick. The best thing, is that it can be tested on a production server with no impact.

Partial page caching

Posted by mgok01 on March 30, 2011 at 5:56am

Hi,

I'm not sure if this is the correct place to ask. I need to improve my drupal performance, so I'm investigating possible solutions: boost, memcache, native drupal DB cache etc.
I've a minor issue: some of the pages contains dynamic data, like counters. the counter is a field of a custom node type. And this field can be updated at the database by some other scripts. So, the anonymous user should see the correct counter value even if we have a caching. Actually we need something like partial page / node caching. The page should be cached but that counter should be taken from DB.

Managing Performance of Drupal when in Maintenance mode

Posted by stewsnooze on March 31, 2011 at 10:39am

One of my sites runs behind two Varnish dedicated servers with something like 12 web servers running Pressflow 6 and four MySQL full InnoDB database servers. This more than handles the load the site runs on.....until.....I put it into maintenance mode.

At this point Varnish stops caching the pages as they aren't sending HTTP 200.

The load average on the Apache/PHP boxes shoots very quickly to above 100 and in general the boxes are looking for cliffs to jump off.

I'm wondering what others do about this.

I think these are some options.

Multi-VM Performance Tuning

Posted by repoman on March 31, 2011 at 7:28pm

Our production environment takes roughly 7 secs to fully render, of which it doesn't start rending until 3.4 secs. So rather than attempting all the great information listed here we built an identical Staging environment with the same exact setup as production. I will include our AB stats along with all the configuration information in hope that some of you might be able to point me in the right direction.

Any help would be greatly appreciated.

Can a pull based CDN be used inplace of shared file system for multiple webnodes?

Posted by ajayg on April 1, 2011 at 8:37pm

If you have multiple webnodes , you need some kind of shared filesystem to sync uploaded files, static files etc.

Instead, what if you use a pull based CDN system. So all your files can be served from cdn1.yourdomain.com and all webnodes point to CDN.
the benefits are
1) You don't need to worry about managing a shared file system
2) You also get a free frontend to server static files.

This looks like a much tempting option than shared file system. Do you agree? Or there are gotchas I am not thinking through?

Experience with LiquidWeb's Storm on Demand "cloud" hosting?

Posted by KingMoore on April 7, 2011 at 4:28pm

Hello!

I'm thinking of moving a somewhat high traffic site off of a Verio VPS to LiquidWeb's Storm on Demand cloud hosting:

I love the ability of our Verio VPS to scale up and down, but during high volume times the VPS isn't really enough.

Pressflow for logged in users + anonymous?

Posted by mrwhizkid on April 9, 2011 at 6:53pm

Hi everyone,

I decided to try Pressflow out today. It seems to work pretty well when I when I replaced Drupal core with it but so far I haven't gotten Varnish to work with it. I did install Varnish but I've had some trouble with getting it to work on my server. Here are a few questions I'm hoping someone could help me with:
