Hi,
From some days, I try to configure a new server, with openvz.
Not so hard, google is very helpfull.
But to finish, and optimize Container and main Server, it is a little hard, and I find some "strange" things.
OpenVz is know as consuming only few ressources. And for me, it is not the case.
Generally :
surfing on website is ok.
The rest is often, very slow, for exemple using DirecAdmin panel.
An exemple of message in Directadmin :
Your connection has timed out
Détails
Either your request was invalid or the program hasn't completed your request.
Please notify the server admin
Or just a command like
yum install <something> is very very long.
Server is 4x 2x 2.66+ GHz with RAM 12Go.
Linux ks312650.kimsufi.com 2.6.18-194.8.1.el5.028stab070.2 #1 SMP Tue Jul 6 14:55:39 MSD 2010 x86_64 x86_64 x86_64 GNU/Linux
Only one website is running on one container. Ok, there is a lot of connection, but this website took 25% of ressources of the previous server (2*2*2.33Ghz + RAM 4Go - not with openvz), so not so big.
Top of server :

What is strange for me :

I prepare 3 containers.
1 is working
1 is connected but without domains or trafis
1 is not active (IP is used on another server) but start.
Top of 1 Container working :

Often load average, 10-20, but always very few cpu%
Often, impossible to connect via FTP connect to read emails

But navigation http without problem, very quick.
