List of good online Website Performance Testing options

pingdom tools is my favourite "site"
http://tools.pingdom.com
http://tools.pingdom.com/fpt/#!/zjJnxpcZh/http://xenforo.com/community/

But to be honest, there are tones of plugins for testing performance:

There are lots more tools listed here (you can add this to your similar lists):
https://developers.google.com/speed/tools

Personaly I use PageSpeed and YSlow, make all the necessary changes to get optimum performance then use Pingdom tools (for a final improvement)

I've managed to get 99/100 for http://www.rightsfortenants.co.uk/forum/ For most forum pages, but that was a while ago, and it's a very stripped down forum

You can see that it is very optimised: http://tools.pingdom.com/fpt/#!/riSy1cTy9/http://www.rightsfortenants.co.uk/forum/
(1 html packet, then 3 parallel requests, then the last 3 parallel requests)
The server is a shared server (not particularly fast), but it's as optimised as it can be without using a content delivery network for my images and scripts

This site was more of a test to see how extreme I could optimise the performance, I'll do a smilar thing with XenForo at some point
 
Bookmarked for future looks. Man, that pingdom is going to be handy. It's already told me I have some javascript calls to something I took off the site a long time ago.
 
I am using this: https://developers.google.com/speed/docs/insights/using_chrome it helps me alot when i work on some sites.

At the beginning I used those tools that were mentioned here.

But later I found out that they don't show what they don't handle with, or they give a minimal attention to those elements, which are surely needed to make websites load faster.

That brought us develop our own parser which makes websites much more speedy loaded,

and I just use the tool Http Archive Viewer which shows a good picture of the waterfall – and I show webmasters the differences of their website's waterfall, with our parser and without it.

(If anyone wonders how it is called then we call it HtmlSpeed)

What's wrong with the webpagetest.org waterfall ?
 
Webpagetest is fine but I measure from local host and not from the cloud.
That’s why I use Crome's measurement and show it's waterfall on Http Archive Viewer.
