Google groups performance

I have been researching running Android x86 in Xen.  The Android x86 mailing lists are hosted on Google Groups.  This has been driving me crazy.   The web page performance is terrible.   I have tried in Firefox and Chrome.   The performance on my tablet is bad as well. On top of the, the arrow keys don't work.  I had to use the mouse to scroll down.  I found the website to be a very inefficient method for giving out information.
