What slows a site down?

I have noticed my site has gotten slower over the last few days. I contacted my host and they said they installed something which should boost performance. Then told me it could be on my end. I am on a private server which should be pretty quick, so i am wondering what sloes a site down?

Could be too many bots hitting it at the same time. There are a lot of bad ones out there

I would think on a private server it still shouldn't be that slow? Usually just shows around 30-40 users? Is there a way to speed it up? Mod, addon ect...

Private server? Do you mean dedicated, not shared?

If you are on a dedicated server, you most likely will have the ability to access the server logs. Take a look a peak times and then examine the logs at that point. It is useful to grab a log analyzer to parse through the data.

Do you have root access? Are you on a VPS or shared?

Test it here on many browsers, many connections, and it goves you tips and tricks on how to improve:

Your host's call center agents - their first and only job is to blame YOU. Keep that in mind.

Here's today's, just ran:

It timed out on Chrome here, your vBShout locked it up: http://www.webpagetest.org/result/13...3KF/1/details/

Firefox, timed out too: http://www.webpagetest.org/result/131023_8K_13MZ/

They do help

I have not. Both or just 1?

You have many problems Mods won't address. You can learn ALOT from the webpagetest dot org site.

So what does that mean? Need to change something?

use both i posted above

If you look at your test results you can see exactly what is slowing you down.

The programs mentioned above are fine, but I would hold off with using them for now. After reviewing your site you need to analyze your host first. @Max_Taxable was trying to tell you that your hosts times seem terrible.

Use one of the many free web testing tools out there and examine your host. Make sure you test from different locations around the world. If it is just a local board then do not worry about a continent halfway around the world.

If you are aware of other web sites that share your server, test them as well. Once you have established that your host times are in order you can then move on and critique your page speed. Start by fixing your errors on your site and using the default templates with your plugins disabled -- to benchmark.

Hope this helps :)

All of your calls are there, and the graph shows you how long it takes each of them to load.

And his own test he ran at Meehan just told him that too:

http://www.webpagetest.org/result/13...21E/1/details/

First byte time is his host, and really that's the least of his issues at this point.

To the OP: To get a baseline reading on your site from WebPageTest dot org, make the vBulletin default style the default style for your site, turn off all plugins, then run the test. This will let you know the difference the custom skin and all the add-ons and plugins are making.

Ok what is the best way to disable all plugins at once?

Instead of rewriting a good post let me refer you to this:
https://vborg.vbsupport.ru/showpost....6&postcount=76

Since you have access to your ACP, and if you don't feel comfortable doing the manual edit.

You can turn off the Plugins from the Admin CP:

Admin CP -> vBulletin Options -> Plugin/Hook System -> Enable Plugin/Hook System -> No

What if you open your config.php file and it already has that? And have a second config.php.new?

If it has that code in the config then no plugins will be used. Which is what you want to do on a test.

Code:

define('DISABLE_HOOKS', true);

Also, you have alot of js that isn't being gzipped or cached. Your other static content such as images aren't being cached either from the looks of it. My guide can help with that, look in sig.

Are you sure it is not commented out, looking like this?

Code:

//define('DISABLE_HOOKS', true);

Yes thats it :erm:

Should the config.php.new still be there?

No, you don't need the config.php.new file as long as you have a config.php file there, unless you want to use it as a backup incase you change something that you can't fix in the config.php file.

Thanks i will check it out. really not understanding what the Not being cached is?

If you need help implementing the htaccess code, then post your original .htaccess & I'll modify it for you in the guide. Also, here's a explanation of caching.

Where will i get the .htaccess? I will post it for you

It can be found in the forum root via ftp if you've uploaded one. If you haven't uploaded/made one, then you can just copy/paste the code from the guide into a new one :D

It keep saying upload failed here. I'm lost lol

In that case try to simply create a .htaccess file via your ftp client.

Once done, insert this and save.

Code:

# Author: Final Kaoss (aka: Extreme-Gaming)

# Version 3.0

# Special Thanks Goes to W3Total Cache for much of the htaccess rules

RewriteEngine on



# This file is only needed if you have set the Forum Component URL in your admincp and you are

# using the mod_rewrite option for friendly urls.  If this is the case, copy this file

# to your forum component stub directory.



# If you are having problems or are using VirtualDocumentRoot, uncomment this line and set it to your forum component directory.

# RewriteBase /vbtest/



# If you are having problems with the rewrite from content/ to content.php, uncomment this line to turn MultiViews off.

 Options -MultiViews

#add your friendly url rewrite rules below.



#stop adding your friendly url rewrite rules here.





#Deny attempts to view the Htaccess file.

And i noticed it is completely blank?

... are you using an Apple os? BC I just downloaded my attachment minutes before you posted, to check some stuff and the files show fine for me on windows. At any rate, you should be able to either make a .htaccess via ftp or create a dummy .html file and rename the whole thing to .htaccess and then doing the above.

And that's your current .htaccess? You can paste the code I wrote above into it & save then.

Looking at those results tells alot. Look at the first byte time - there are NO Mods or optimizations or .htaccess that will address that. That is your host.

However, did you notice how much speed you picked up just disabling the add-ons?

OK awesome, anything else you just the exact code?

With the exact code it will help your loading times & reduce server load by not loading as many resources by quite a bit.

If you feel it is still slow, you may want to pursue some of the other steps I wrote as well. If your host doesn't improve it's performance then you will see long "time to first byte" times. In that case I recommend flipperhost.

Yep I am very familiar with that. It has nothing to do with first byte time from server, and also you might note the OP is doing all of his tests thus far using Firefox:

That article is all about supporting IE better.;)

Quote:

This information is ammunition to give to your current host, proving the first byte time from the server is quite slow. Changing hosts won't guarantee you better first byte time.

But the BIG stuff is, the amount of problems alot of your add-ons are causing.
