High Performance

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.

If you think you have found a bug, use the issue queue for the appropriate project.

wrong mod_fcgid configuration?

Posted by muschpusch on May 5, 2011 at 10:41am

Hey!

i just switched to mod_fcgid and the response time of sites is good until i benchmark them :)

Under multiple concurrent requests (ab -c 50 -n10000) i get notices like this:

[Thu May 05 12:16:37 2011] [notice] mod_fcgid: /var/spool/www/user/aegir/drupal-7/index.php total process count 15 >= 15, skip the spawn request

and the server performs really really bad.

My mod_fcgid config:

AddHandler fcgid-script .fcgi .php # Where to look for the php.ini file? DefaultInitEnv PHPRC "/etc/php5/cgi"

mod_fcgid & apc

Hey,

i read a lot at 2bits.com and decided to switch from mod_php to mod_fcgid. Now it seems like my apc cache is empty. (apc.php statistics says so). Do I need a special apc config? This is my apc.ini

extension=apc.so

apc.optimization=0
#SHMMAX is changed
apc.shm_size="480M"
apc.ttl=86400
apc.user_ttl=7200
apc.stat=1
apc.user_ttl=7200
apc.num_files_hint=0
apc.mmap_file_mask=/tmp/apc.XXXXXX
apc.cache_by_default=1
apc.rfc1867 = 1
apc.enable_cli=0

Kind regards!

Memcache module with Drupal 6.20 in a socket situation at WebFaction, and NGINX

Posted by Miko. on May 3, 2011 at 8:47pm

From previous posting to this group the Special Olympics of Northern California and Nevada decided to try Webfaction for several reasons, but two of there were

a) that I was told it had memcache that we could use and also was
b) told that the nginx server would help with serving static files.

Well neither seems possible, unless someone can help. All help is appreciated by myself and the Special Olympics.

Dear Drupal community,

We would like some advice and maybe further collaborations regarding a Drupal-based project, specifically concerning performance issues.

High traffic volume sites with high accuracy statistics

Posted by xaris.tsimpouris on April 27, 2011 at 4:28pm

Hi,

The problem:
For every post, I want to show the exact number it has been viewed by everybody, anonymous or not.
This does not only include showing in every post page, but also in views with results of various posts.

Huge number of user accounts: which impact on performance?

Posted by zezaz on April 21, 2011 at 4:46pm

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,

Tweaking the file system (files/*)

Posted by bserem on April 21, 2011 at 10:43am

I recently (yesterday) got my hands dirty with a huge news-site in Greece that suffers from really bad performance!

I checked the filesystem and saw that the previous admins placed all files under the "sites/default/files" folder, without creating subdirectories. Now there are more than 20000 files under there, increasing by 100 per day.

Could this be the source of all evil? The owners of the site say that the problems are getting worse every month so I imagined that by re-arranging files in the file-system I would gain something in performance.

I had our sysadmin install APC and it tested as slower then before he installed it.

Is this possible?

IS this normal or memory leak?

Posted by ajayg on April 18, 2011 at 4:36am

I have a separate server for Mysql. I am noticing that the amount of used memory shown by Top is gradually increasing.
I don't have anything else on the server (no php) except for basic OS (fedora 13)

Some tables are myisam and some are innoDB. Used drupal 6.x so started originally with myisam and converted a few to innodb as required.

I know mysql is memory hog. But is this normal? Is there a way to tail MYSQL to have a limit?

Quite popular site so is this a result of number of connecttion? But then shouldn't it release the memory as time goes?

drupal 7

Posted by socialtalker on April 15, 2011 at 4:04am

i decided to go with drupal 7 instead of pressflow, but i am not at all clear what are the steps to make drupal 7 perform faster. is there some kind of instructions listed anywhere? I know about the boost module, for example. I have heard of stuff like squid and varnish, but do i use that will drupal 7?
