Managing suEXEC Fcgid Processes with APC

Posted by Daeluin on February 17, 2011 at 9:11pm

First, many thanks for the invaluable tuning discussions/resources here and on 2bits. They've been most helpful.

Lately I've been testing a change from:
mpm_prefork
suEXEC
suPHP
zend Optimizer

to the recommended:
mpm_worker
suEXEC
mod_fcgid (2.3.6)
APC (3.1.7)

I mainly followed the excellent instructions and relative values used here: http://2bits.com/articles/apache-fcgid-acceptable-performance-and-better...

How do we deal with spikes of usage with Drupal behind Varnish

Posted by repoman on February 18, 2011 at 6:39pm

Setup:

We are running pressflow behind a varnish proxy on two separate VMs all in a RH LAMP environment. We host internally so we have full control over the environment but just lack the expertise to fine tune this.

Issue:

Drupal Bigpipe Implementation

Posted by denny84 on February 21, 2011 at 5:50am

Its not new but I recently came across this article on how to decrease page rendering times using "bigpipe". There is an implementation for the same technology on github.

Has anyone thought about implementing Bigpipe for drupal? This is going to be a huge performance hit. How difficult is this going to be? Currently Drupal doesnt yet support similar header approach.

Scaling Plan for Novice

Posted by dereckd on February 24, 2011 at 5:08pm

I've tried to go through the groups and forums to glean as much information as I could prior to posting this. I fall into the category of someone who is fairly familiar with drupal and mildly familiar with server setups. There is a wealth information on Performance and tuning, but it leaves the novice without a clear path of how to scale. I though I would post my setup here along with my confusion, in hopes that it will help other individuals in the same boat.

My Current Setup
I currently have 400K nodes and 100 users
I hope to be able to scale to 100k + users 5M Nodes

Solutions to annoying CDN behaviors

Posted by mshmsh5000 on February 28, 2011 at 10:03pm

In our stable of D6/PF6 publishing sites, several have these qualities in common:

Delivered by Akamai.
/admin and other sensitive paths are locked out of the public site (example.com/admin) and available only on our internal network (e.g., internal.example.com/admin).
Cookies are shared on the domain level (.example.com).
admin_menu enabled.
Akamai is set to ignore the app's cache-control headers in certain places, or across the whole site.

Best practice shared file system

Posted by adrifl on March 1, 2011 at 2:18pm

We run a large Pressflow site with several webservers (load balanced with HAProxy). On every server the pressflow /files directory is shared via NFS3 to a master server. We see some limits in this NFS approach and would like to deploy a new, more performant and redundant system.
There are different choices like GlusterFS, MogileFS, NFS4, Lustre, ...
What do you use and how are your experiences so far with shared file systems?

Thanks for any best practice hints.

Need MAJOR Help Understanding If Drupal Will Work For Us- Complete Performance Novice Here

Posted by Miko. on March 1, 2011 at 8:28pm

I need help determining if we can really use Drupal and MySQL for a new site being planned for the Special Olympics of Northern California. I just read through another thread here by a "novice" and that "novice" knows WAY more than I do, so please know that while I'm a good Drupal designer, I know NOTHING about real performance issues.

The Special Olympics has a limited budget and I, nor anyone, will be setting up and managing the server configuration. We are looking at commercial hosts like GoDaddy.com and I'd like to use GoDaddy if it's not ridiculous for our needs.

I have been reading the last couple of months this drupal group and learned a lott of caching and performance.

Specifications:
Now i'm running Apache with Boost,memcache and Drupal6
VPS with 1GB RAM but we can boost this up if we like to 4GB.

High Availability (HA) - Drupal

Posted by alexus on March 3, 2011 at 5:24pm

We’re trying to ascertain the best way to achieve good redundancy in an enterprise-level utilization of Drupal. Ideally, We would like to have multiple instances of Drupal on different physical hosts/VMs. For instance, if we need to perform maintenance on one host/VM, the site doesn’t go down because there’s always another instance up, or in case of DOS attack, we’d have a better chance of sustaining because we’d have multiple instances running instead of one.

Have others been able to achieved something like this? Any advice, caveats or suggestions?

File Cache - benchmarks needed

Posted by ogi on March 4, 2011 at 9:13pm

Hi,

I've just released first alpha of File Cache module and it will "compete" mainly with memcache and (to a lesser degree) boost. In my tests File Cache consistently outperforms memcache by very small margin and I would like test results by someone else :-) It's interesting to benchmark File Cache on memory filesystem too.
