Hello,
We operate with our own VPS node and run OpenVZ with SolusVM.
I have created VPS and install Virtualmin/Webmin on it. I have used Virtualmin repositories ( http://software.virtualmin.com/bleed/centos/5/i386/virtualmin-bleed-rele... ) and epel repositories (http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarc...) so i can run php 5.2.17 and phpmyadmin last version.
I have not done anything other inordinate with installation and configuration the VPS and i have follow the tutorial on Virtualmin wiki. I use Centos 5 x86 image that i have downloaded from openvz.
But even i have reinstall and reconfigure my VPS 2-3 times i have problem when there are 50+ visitors online the website load from super fast is starting to load extremely slow! The VPS and the node load are low. The VPS load is less then 0.7 and the node load not more than 1.5. There are plenty of RAM and free network connection ( from 100mbps i use only 4-5 MAX ). My Node specification is i7 980X with 24GB of ram. I have notice the same problem on 2 different VPS i crate and install/configure with Virtualmin/Webmin. And both VPS are running different websites ( one is joomla and the second is wordpress ). Does anyone have any idea what can be the problem? Why even the VPS load is very low the websites are loading very, very slowly.
I accept any help!
Howdy,
If I had to guess, it would be that there's some sort of issue with the resources allocated to the nodes in question.
Joomla and WordPress are typically pretty speedy, even on a VPS with 512MB of RAM.
So if what you're seeing is just a handful of users generating light usage -- the first explanation I can think of would be that the nodes don't have enough resources (I'm not overly familiar with OpenVZ setup, but you may want to verify that they have enough CPU and RAM dedicated to them).
The only other thing is if some application was taking up a lot of resources... you could use something like "top" to watch the processes that are running, and you can verify that it really is that light usage of Joomla and Wordpress that's causing the issue.

Hello,
The Hardware Node is having lot of free CPU and RAM. RAM: 3.08 GB of 23.48 GB used / 20.4 GB free LOAD: 1.13, 1.90, 1.10 H/W RAID10 setup 1.5TB HDD`s 100mbps network link ( Tested 93mbps free only 1-3mbps used )

Any other idea ?
it looks like that VPS has 1GB of ram. However that should still be enough for a joomla site.
Did you try to create a VPS with a different images?
also if you create a vps and put the website on it without virtualmin, do you notice a difference?
Just to rule out chances 1 by 1
it isn't easy to troubleshoot such environment over a forum though virtualmin should not have any negative impact on performance.
I tend to be suspicious of OpenVZ though...
For such a monster host machine, depending on the number of VPS you wish to operate, I highly suggest running the free version of VMWare ESXi. My experience with that is 100% positive in terms of performance and stability.
It also tends to produce less problems with Linux guest servers than OpenVZ. There are regular forum posts here about OpenVZ related problems.
