Idea Kunena getting Slowwww! Ddos attack or normal behaviour?

It's about 2-3 seconds in non peak time and 30-70secs in peak times.

Can the integration with Jomsocial cause such delay?

Apart of that Kunena is working great.

Looks like your server runs out of resources when it's busy.

This could not be Joomla issue at all: please check if your Apache has keepalive turned on. If it has -- please either turn it off or have more useful number in there, like 3-5 seconds (= enough to load all files for one page). In many cases this will make your site a lot of faster during peak hours.

Few days ago I replied that this kind of slowdown is usually mark of server resource saturation (eg. running out of CPU, I/O or memory). In that case making page loads even slightly faster can fix the issue (use caching, uninstall all unused plugins, remove modules that you do not need, disable Kunena integration etc).

I'm in process of writing this wiki article:
docs.kunena.org/index.php/Improving_Kunena_performance

It's still work in progress and not very useful, but I will try to find some time to improve it.

I also welcome everyone to help me and give your own ideas on how to improve site performance.

Good news: this slowdown was caused from a bug in JomSocial 2.4.0 and 2.4.1, which forced all users to be recalculated saved on every page load (meaning 400 extra queries in my test forum).

Hi Matias,

Thank you very much for all your insights.
I have my Apoache Config thought for high usage:

My apache config is:
Timeout 30 /etc/apache2/apache2.conf (13)
KeepAlive On /etc/apache2/apache2.conf (14)
MaxKeepAliveRequests 30 /etc/apache2/apache2.conf (15)
KeepAliveTimeout 5 /etc/apache2/apache2.conf (16)
<IfModule mpm_prefork_module> /etc/apache2/apache2.conf (25)
StartServers 10 /etc/apache2/apache2.conf (26)
MinSpareServers 3 /etc/apache2/apache2.conf (27)
MaxSpareServers 8 /etc/apache2/apache2.conf (28)
MaxClients 100 /etc/apache2/apache2.conf (29)
MaxRequestsPerChild 4000 /etc/apache2/apache2.conf (30)
</IfModule>

Maybe one problem is that I have the cache disabled because members see the wrong information when I activate the cache.
Anyway since I disabled Kunena JE latest all is better now.

Best regards and thank very much again,
Carla

I study my slow load sites in webpagetest.org (I'm sure most of us have used it) and it keeps telling me my Kunena component is by far the slowest due to Mootools-core.js and Mootools-more.js components. Is there a way to make this faster. These seem to be 80 percent of my sites resources at the moment. Anyway to fix that?
