high performance

Hi,

I wanted to get feedback about whether releasing our module sounds like a good idea.

Our company has developed a module that publishes static Drupal nodes to S3 as they are saved or during a full site crawl. We've used this on a few projects where there is a need to cope with large traffic spikes (e.g. websites that support TV broadcasts) and where the content is relatively simple but there is still a need for content management. So quite niche but hopefully useful to some.

Just recently setup new relic for a site and was surprised to see how much of the server's response time is being spent on memcache reads/writes. On a sample response, the breakdown is something like this:

PHP: 312 ms
Database: 143 ms
Memcache: 201 ms
External Web Service: 17 ms

Am I correct in thinking the memcache time is way too high? Or is this similar to other people's experience?

Thanks in advance for your thoughts.

The folks at 10gen are offering 2 free courses in MongoDB (see https://education.10gen.com/) - one on creating applications using MongoDB and a second on deploying and administering MongoDB. From what the site says, you will also receive a certificate upon successful completion of the course. I've signed up for the latter so far (and hopefully if the program continues, sign up for the former next year). As I already mentioned, the courses are free but you have to sign up before the first set of homework is due on Monday the 29th.

I work for a company that installed drupal about a year ago.

We provide content management services for a particular market niche.

We're currently doing OK mysql wise with a master feeding a slave backup server. However, we're growing pretty quickly and we may need a higher performance architecture in a year or so.

We're also very keen for the system to be very robust, and the time required for failover to the backup db server gives us some heartburn.

Sooo.....

I'm working on a couple of applications that will deploy on EC2, and we're having a hell of a time getting error output (calls to error_log(), php errors, etc.) sent to anything but a text error log.

Any ideas as to what the issue is here? Is this even possible right now with php5-fpm and nginx????

Here's what I've tried.

Going to a text log is easy enough if we put

into a pool configuration for php5-fpm on Ubuntu (11.10 at the moment).

So if I do
<?php

ok , example first to prove that i am telling the truth : http://trackself.sinaapp.com/ just feel its speed!

[background:]
1.SAE: sina app engine , belong to sina.com (China), it's a service like google app engine ,but provide PHP hosting and mysql hosting and more! well , i think it's better than GAE, because i only know php but not python/java. It declare itself cloud service. And better than GAE, it use SVN.
2.Since it offer php and mysql hosting , drupal can be hosted. But a little hack to install.php , nothing more hack

p>I have a site running Pressflow (Drupal 6), Varnish, Memcached, and APC with the Cache Router module. I'm unsure why but APC is restarting every 10-20 minutes. If I review the stats page (see the attached image) the uptime will increase to somewhere between 10 and 20 minutes. As I click the "refresh data" button I'll see a second cache set shown with an uptime of 0 or 1 minute, and each click of refresh data will toggle between uptime of 15 minutes and uptime of 1 minute. Eventually the 15 minute uptime disappears and I only see the 1 minute uptime...

Hello,

I am going to create a D6-based web site for a huge number of users ( > 800,000). We expect this site to have tens of thousands of nodes (>20,000).

What is the impact on performance of these? I could not find any info on scaling the user accounts number. Does it make absolutely no problem performance-wise to have so many user accounts?

Here is what i managed to gather until now:
- i should use the SOLR module for my search engine, because the vanilla Drupal search engine will not scale to that nodes number,

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.

Hi everyone - New Relic is here at DrupalCon and we've had a ton of conversations with folks here about drupal performance and visibility into Drupal's behavior. Dries' even mentioned it as a core pillar moving forward at his keynote. We're focused on performance and want to make sure we open up the ability for anyone in the Drupal community to sign up for our free month program. Sign up here: https://rpm.newrelic.com/signup/18 and enter the promo code "DRUPALCON" . For more information, read Dries' blog post. http://buytaert.net/playing-with-new-relic-on-acquia-hosting
