Zoho Mail and Google Chrome High CPU Memory Usage

Zoho Mail and Google Chrome High CPU Memory Usage

Is anyone else getting extreamlly high CPU usage with Zoho Mail and Calendar?  Using this URL https://mail.zoho.com/biz/index.do .  I am getting around 30% CPU usage.  It goes away after I refresh the page but it happens very frequently.  

I have tried all the obvious things.  Disabling extensions, shockwave flash, etc.  No luck with anything.  Help is appreciated.

Thank you,

-David
