In the Chrome browser there is an awesome tool to check the load speed of various parts of your web site. Also, you can confirm that the server response codes such as 301 redirect are working OK.

Also, you can see how many HTTP requests are involved when delivering your page, and how fast the DOM (code) is loaded compared to the whole page with images etc.

I just press F12 to access this tool.

Here is a screen shot of one of my sites in the Network Tab showing the load times.
