Page Speed Issues - web

Really having lots of page speed issues, my web developer tried a cdn for the banner loading which made it really fast, but now she has amended this and the speed has really dropped very low again.
Any suggestions on howto rectify this?

Without having any more information on your site it is very difficult to help you out. Have you tried using tools that tell you where your site is being slow and provide recommendations, for example Google Page Speed Insights?

Domain redirecting without my permission

http://catbreedsinformation.com
A friend and I put that site together a few years ago, just to do some study on how to use google ranking. It was actually doing quite well. Recently, we haven't really messed with it, but I still check the analytics, and they have severely dropped.
I went to visit the site tonight, and it loads for a split second, and then redirects me to a completely different site.
Can anyone explain what is causing this? And also, explain how I can stop this?
thanks.
Looks like your website hacked.
First of all, please change all passwords. Then remove twitter fan box plugin (because script of this plugin is causing redirect)
Then you can check this resource: https://codex.wordpress.org/FAQ_My_site_was_hacked

How to profile browser page load using Javascript (Library)?

I've been doing a lot of research on this, but I figure I could crowd-source with what I have and see if anyone can offer additions to what I have. So I want to be able to determine page load time using JS. Not just page load as a single number, but as a breakdown.
First what I found was a new W3C Specification (Draft):
https://dvcs.w3.org/hg/webperf/raw-file/tip/specs/NavigationTiming/Overview.html
This would be perfect, however its limited to Chrome, and IE, and it's still inconsistent between the browsers.
But now I have found Real User Monitoring (RUM) by New Relic that is based off of a Javascript Library by Steve Souders. From what I can tell they can determine the same data that I saw from the new w3c Draft.
It seems that they are using HTTP Archive: http://code.google.com/p/httparchive/
However, I cannot seem to find any information on page performance or load, so I wasn't sure if I was looking at the correct library.
Now of course, if there is anything else out there, that could provide more information on page profiling, I am welcomed to the information.
Have a look at Boomerang.js (https://github.com/yahoo/boomerang) by Yahoo.
Should allow you to roll your own RUM and does graceful degradation so you should still get some information from browsers without navigation.timing.
Also if you've got access to Windows have a play with dynatrace's tools - gives quite a good insight into what it going on during page load (in IE and FF)

You can use web-browser developer tool.
For Chrome, tools are embedded in the browser:

For Firefox you can use the Firebug plugin:

How can I see how much bandwidth my website uses?

I'm looking for a Firefox addon which will track how much bandwidth a page is using. This could be a regular HTML page or GMail with the chat feature using Javascript. Is there anything that will help me optimize my page like this?
Perhaps YSlow is what you're looking for?
FireBug has function that allows you to see how much bandwidth and how long certain scripts, pages, images, etc take to load
Install Firebug
Download YSlow
Review the YSlow User Guide
