Nexus 7 and Android 5.0.2 - Lag Fix

So I'm not a heavy tablet user, but I did manage to snag a Nexus 7 (8GB) for free at a conference a few years ago.

I had initially thought that this was likely due just to NEW OS and OLD hardware. However after doing some digging last night I came across a number of suggestions to wipe the cache partition. Instructions can be found here: How to wipe cache partition Nexus 7 or like this.
