How to solve the problem with lags on nexus7?

Question

Android

Good afternoon, the problem is this, the nexus 7 2012 started to slow down a lot, the RAM was half busy, when the media services stopped, and the recovery wiped the cache, there were fewer lags, but not much, in games especially 3d lags sooooo much, some do not start at all.

On Nexus 7 2012, you need to regularly run fstrim -v / data (well, the rest of the mount points will not hurt - / cache, / system) in the recovery terminal (I'm talking about TWRP) so that there are fewer problems. And if you flash a normal firmware and install ParrotMod, then a new life begins. I'm using The Pure Nexus Project firmware (Android 6.0). In my opinion, Google services (GApps) should not be installed, but applications should be installed through the Yalp Store.
