Those are the load times I am getting when I go into debug.

I am pretty sure that these are high, even for my site. I only get about 100 people on simultaneously, no more than that. I do have a several addons installed, but I am not so sure if that is the problem or not. If anyone can help optimize this or at least let me know where I could go about optimizing it, would be really appreciated. Thank you :)

Edit: More infromation

At the time of this screenshot I have the following members online: Online now: 157 (members: 30, guests: 127)

That's many more queries than I see on my pages - but it still should not make a big difference. My old forum often used 30-50 queries per page!

My guess is that you are on a shared server and the problem is elsewhere. Have you done a top command (unix) to see how busy the actual server is?

Windows or Linux server?
RAM?
Basic hosting, VPS, Shared or Dedicated server?
Any other sites or applications on the same server?
If you can find it/know what it is - can you post a copy of your my.cnf MySQL configuration file?

Cheers,
Shaun :D

Okay well I am using a VPS server. It has 2gigs of ram, I am currently running Plesk 10 on it. This is a Linux server running CentOS. Also I do not know where the my.cnf file is but if you could give me the location I'll post it here. I am also not running any other applications on the vps besides the actual website, and centos/plesk.

Could you tell me how to do this command, so I can check how busy my VPS really is. By the way, I am not on shared hosting, I am running a VPS with 2 gigs of ram.

Well, my assumption is that if you have a true VPS, the server load should be extremely low when you have only a few users on XF. The errors you are getting with your db connections (from your other thread) show that something is configured wrongly.

To do a "top" command, you need access to a command line interface. I would assume most VPS servers have this? 2 Gigs of RAM should be plenty for what you are doing. A stock mysql install should also do the job. I suspect your hosts are going to have to change something in the mysql config or elsewhere.

A "top" screen is enclosed - showing my server load at almost nothing (below 1) and the CPU at 90% idle - and also that the main programs running are apache and mysql.

Realistically, my first move if I were you would be to place a call or email into your hosts and show them that server log from other post and indicate that your mysql installation is not processing without errors.

Has been known to drastically increase number of queries.

Disable this. Now how many queries?

EDIT: This is a suitable replacement for that add-on, should it be found to be causing the problem: http://xenforo.com/community/resources/tinhte-xentag.770/

I have it currently disabled, would removing it make the difference ?

Well I have installed everything my self onto the server, I am assuming that could be the bigger problem. All I simply did was use SolusVM to install CentOS 6.2 and then installed Plesk 10 through putty.

As for if I have access to a command line interface, I am assuming Putty should do the trick, which I indeed do have access to. If you could tell me the command I should run to display the data in your screenshot that would be great.

BTW I am running Plesk 10.

Thanks for the command ....

So here is the screenshot of my server with the "top" command.

How many CPU cores do you have access to? If you press 1 while running top, it will show each CPU individually.

That loads could be considered high, but really depends on the CPUs. How many members were online at the time?

Oh just to clarify this is a XEN Virtualized VPS if that makes any difference.

I have access to 4 I am assuming since I just ran the command that you were talking about and it came up with four. Here is the new screen shot with the 1 being pressed.

At the time of this screenshot I have the following members online: Online now: 157 (members: 30, guests: 127)

Firstly, enabling debugging will drasticly increase your load.

I would suggest disabling all addons, to start with, add this to your config and see what the loads and queries come down to.

Code: 
$config['enableListeners'] = 0;
Do you have any caching mechanism installed such as APC or memcached. Are you using the minify option?

Currently no I have disabled / removed them since I came to the new server none of them are installed.

Although I do have the front end caching in my Config file... this thing
Code: 
$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array(
'caching'                   => true,
'automatic_serialization'   => true,
'lifetime'                  => 3600,
'cache_id_prefix'           => 'xf_'
);

Okay I disabled all addons through that command in my config file and I have approximately 11 database queries now.

Page Time: 2.0806s

Memory: 10.0887 MB (Peak: 13.0035 MB)

Queries (11, time: 0.0281s, 1.4%)


That is what I am getting with all the addons turned off.

It would suggest your problem is with one of your addons then.

Disable them all in admin cp and start re-enabling them one at a time to find out which ones are cauing the most problems.

Also installing apc and memcached will help reduce the loads.

Uhm I think I have a problem here

What do you do when something like this happens

Caasdfasdfptuasdfre.PNG



Just look at the loads, that completely crazy.

and my site now displays

Code: 
An exception occurred: Too many connections in /var/www/vhosts/domainnamehere.com/httpdocs/library/Zend/Db/Adapter/Mysqli.php on line 333

Could my site be under attack or what could lead my server to have such load averages?
