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

how much hard drive space do you have available? what does df -h say? Have you checked /var/log for error files like /var/log/http etc? Maybe something in your coding on your website is generating a huge amount of errors. I had a boss that did that because his coding sux and his name is gary and he worked at bobcad.

The load average is silly high. The MySQL and httpd processes are consuming a lot of CPU time.
Have you installed anything other than the base joomla system? Additonal plugins, your own plugins?
How many users are using this system?
Another thing is MySQL is using little memory which suggests you're using the default configuration. The default configuration minimises resource usage at the expense of performance, it is suitable for use on a development workstation, not a production server.

My website has many users and yes, it is very possible that "MySQL" has the default configuration (I didn't make the server installation)
I have Joomla 1.5.10 and I have 80 plugins installed.

OK, can you quantify "many users" please.
Some information about it's history would be helpful, did it just suddenly start going slow, or has it been getting gradually slower over months? As the number of users increased suddenly. Have you made any changes, installed new plug ins or done a server update recently?
I also note that the box is a virtual machine. What else is running on the host? If the CPUs are over committed then it is feasible this server is being starved of CPU time. If the host was using hardware virtualisation, then could someone have turned this off?

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:

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.

On your latest top results it showed that mysqld is no where to be seen; unlike it's 35% cpu usage in the initial post. There is a high possibility that the slow performance is due to the web server and the mysqld server. Maybe due to high user loads, a backup process being run, a specific user running a lot of queries that taxes the mysqld server, etc.

It's clear that the problem is only solved because nobody is using the machine. Compare the load values in top from when the computer was performing badly and when it was okay. Then compare the number of mysql and http processes between the same two top listings.
The machine is not fixed. It is simply not being used today.

Re: chickenjoy's post: Aghhh. Concurrent typing; similar observations. I hate when that happens. |
Mmmm.... Ok. I will review the web the entire day. But I have a question: Can it be that the restart of "Apache" "MySQL" have something to do?
I do not know exactly how the file system "Apache" and "MySQL" works but, can be posible that something will be consuming a lot of memory has been cleared in the moment restart these services? |

Well Galled I must eat my words. 
Given the number of http processes in the listings shown in reply 14 AND the very low load average it appears that the problem may be resolved.
Let's hope that it stays this way.
Is it possible that the computer was also running backups or updatedb when the problem appeared?
Cheers.
