IspCP limiting my system resources - psygarden - 02-12-2008 07:00 AM
I've been running ispCP for some time now and must say that quite a few websites are running awfully slow if they have a somewhat more cpu-heavy php script running...
My cpu never ever (ever) peaks over 10%, but still sometimes i have to wait 5 seconds for a page to load (or worse, the 500 - internal server error message) ...
i'm quite sure it has to do with the configuration of the fast-cgi parents/children but haven't got a clue how to configure them...
can anyone give me some advice on how to un-limit the cpu usage for all websites?
kind regards,
Rik

try to use the newest php (5.2.5)
and try out our new fastcgi conf located in the trunk.

I've already upgraded to 5.2.5 a few weeks ago (and documented it here) to fix an issue with orphaned fcgi threads that wouldn't get killed
i'll have a look at the fastcgi.conf file you are talking about, is this the file in /etc/... or the individual files in /var/...
?

I think, you already have the *new* fastcgi_ispcp.conf (apache2/mods-enabled/)

You can try to increase the "PHP_FCGI_CHILDREN" in the php-starter.
So that there are enough childs running and wait for the request.

There's something strange about the directory structure that i want to clear out with you, i have this folder:
Quote:/var/www/fcgi/website1.com/php5-fcgi-starter
/var/www/fcgi/website2.com/php5-fcgi-starter
/var/www/fcgi/website3.com/php5-fcgi-starter
but there is also a second folder with the same set of subfolders in this location:
Quote:/var/www/fcgi/fcgi/website1.com/php5-fcgi-starter
/var/www/fcgi/fcgi/website2.com/php5-fcgi-starter
/var/www/fcgi/fcgi/website3.com/php5-fcgi-starter
These folders contain the same data twice for some reason, and i don't understand how they got there... Can you verify your installs that this is normal?
What files should I edit, and do I need to restart anything to make the changes active? (apache, fcgi, ... ?)
greetings,
Rik

I don't have a folder named fcgi in /var/www/fcgi - so the second one should not be there - move it to some other place and check your sites...
to edit, you need to edit the php.ini in /var/www/fcgi/<domain>/php5(or 4)/...
and an apache restart helps to see the changes quickly - you also could stop the phpX-cgi processes, so they are started again with the next site-access.

I think i'm getting closer to the performance i'm used to! Only thing that still catches my attention is the delay before the first pageload of a site that i haven't visited in a while... but that could be caused by several factors...
Could anyone here with a large ispCP host message me an url or two of sites hosted on their server that use cms (phpbb / joomla/ gallery2...) so i can compare the performance? (i'm hosting 10-15 websites on a dualcore amd with 4gb ram)
