VF Home tab - size and loading time

I created a VF Home tab that has a few charts at the top (with tooltips), and below is a section with the Chatter newsfeed on the left and the Activities object on the right (with only 2 filter options, "My Open Tasks" and "My Open Meetings", which doesn't contain tons of data).  The loading time is too long.  First load takes a couple minutes and after that, takes about 7 seconds.  But other than that, everything works excellently.  

The charts are pulling data from a few different objects - Users, Opportunities, and Accounts.  Would it be better to have the charts in a separate VF page and then just pull that VF page into this new VF Home tab?  Any help is appreciated.  

VF:
