My Centos is terribly slow
Hello I have a Centos 5:
Linux xxx.xxx.xxx 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:19:18 EDT 2009 i686 i686 i386 GNU/Linux
Problems:
- When I connect with SSH, each command take until 2 min to run!
- Restart the server takes 16 minutes on average.
- I have a web page in this server (PHP (Joomla) with Apache/2.2.8 (Unix) ) and each page takes 1 min in load.
- I assumed it was because originally it was connected with IPv6, because when running the command "lsmod | grep v6" showed me the following:
ipv6 261473 125
xfrm_nalgo 13381 1 ipv6
But using this website ( http://techno.mayix.net/deshabilitar...-redhatcentos/), I disable IPv6 connection because when running the command "lsmod | grep v6" showed me nothing. But the problems of slowness, still.
- When I run the command top give me this:

Why is this server so slow? What could be happening? Why Apache appear to have many instances created? And why always consumes so much CPU?
P.D.: Sorry for my english

Those Apache children are serving up webpages..otherwise they would not show at the top of your output while running "Top"
Have you checked your access and error logs to see if there's any suspicious activity?
What hardware is in this box? It seems to be overloaded and IMO should not be even with that level of activity. If you notice, the percent of CPU usage adds up to quite a bit more than 100%

I would guess that one of three things are happening:
Your hardware has a major problem
Your software is improperly configured
Your server is under some sort of attack
Have you checked the following for clues?
/var/log/messages
/var/log/secure
/var/log/httpd/ (both access and error logs in there)

Is this a physical system or a virtual machine?

Initially I assumed it was a real machine, but then appears to be a "VMWare" but do not yet know the version.

Ok.... Mmmm. This is so weird. I just conect with my server by SSH and now it's fast!
It is possible that a requirement to note the speed of the server after changing the settings by disabling the "IPv6" is restarting the client? Because that's all I've done and now the site loads fast and the connection via SSH is fast too!
Now "top" showed me this:

And "df -h" showed me this:
Code:
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 5.8G 2.2G 3.4G 39% /
/dev/sda1 99M 22M 73M 23% /boot
/dev/mapper/gv1-vl1 30G 21G 7.1G 75% /var
tmpfs 760M 0 760M 0% /dev/shm
And in "free -m" I have this
Code:
total used free shared buffers cached
Mem: 1518 1454 64 0 59 1089
-/+ buffers/cache: 304 1213

As far as I know, since the friday nobody has touched the server and the only thing I did was simply restart my pc.
I will continue to monitor the server during the day to verify that the problem is solved.
Thank you very much for all your help and your time!
P.D.:I have reviewed the "history" and an administrator has restarted the "Apache" and "MySQL". I supose he has made a modify of some config file of this services, but in the "history" trail does show nothing similar to "vi" or "gedit". He may have done this change by FTP or another way.

I talk to an administrator. He has replaced the entire virtual machine Centos 32-bit to a "Ubuntu Sever 10.10" and has installed the apache in worker mode and fast-cgi php. He has made in the weekend.
Bone in the end the solution was to change the OS. XD
