Web interface is slow

[SCOTT No2]

Recently, when I log into my switches (SG350X-48), the webpage is super slow to load.  it shows "processing data 60%".   then sometimes it stops. sometimes it doesn't finish.  sometimes it does load but the graphics (links to pictures) are missing. 

I have a few of the SG350x-48s in 3 separate stacks.  Each stack seems to do the same slow-load.  I thought it was my browser (Firefox) but it happens on other browsers.  Also this browser is set to delete cache and cookies at close. 

What can I do to speed this up? or is this just how it is?  Reboot (which takes down the network)?  Any general thoughts?

Thanks.

Login SSH and check the logs, most of the suggestion reboot (in the maintenance window)

Thank you for your response.  (This is going to be a bad question)  How do I reboot the switch?  The original engineer left and i took over; I'm trying to learn how to run these switches.  thanks.
