Access page freezes when there are a lot of access sessions populating

We have 6400 access sessions with an access session group called "All Machines". That's the group we're in most often because it is easy to search for the machine you need, however if you don't search quick enough the whole Access page freezes and you can't click anything because it hangs on populating that many machines. Once the sessions populate, the page is horribly slow. If I click on another access session group with fewer machines (like 50), I see the URL update to the right group, but the page is still frozen. That's in Chrome. The same behavior is in IE, but it's not as sluggish after all the access sessions populate. FireFox behaves the same way, and is a little better than Chrome after the sessions populate but still more sluggish than IE. Would love to see some performance improvements so we aren't quickly trying to search before the page gets hung.

Effected browsers:

Chrome 57.0.2987.110 64-bit

IE 11.953.14393.0

FireFox 52.0 32-bit

OS I'm accessing SC from: Windows 10 Anniversary Edition

This is also an on-prem version of SC. Our version of SC is currently 6.0.11622, but this has always been an issue.
