Zoho CRM Canvas is slow in loading

Zoho CRM Canvas is slow in loading

Hi, the new Canvas feature in Zoho CRM is very interesting but the layout becomes very slow to load. I mean using the standard layout for Contacts detail view takes about 2,200 ms to completely load the page on my Chromebook (and my connection speed is good, about 150 Mbps), but using the canvas view (with less data than the standard layout and a lot of lazy loading with tabbed views) takes about 8,500 ms! It's around 4 times slower. Too much.
Is anyone experiencing the same problem? 
What can you do to speed up the page load?
