Question [Q] 2012 Nexus 7 - CyanogenMod fix the laggy speed?

Does changing over CyanogenMod on a 2012 Nexus 7 Wifi 32GB, fix the extreme bad performance?

Or is it time to junk it?
There is 25+ GB free on the device, ran the memory cleanup apps, still junk. Any of the apps I try and use random freeze for 5+ seconds at a time, it is slower than my nexus 4 by far. The nexus 4 runs circles around the nexus 7.

Will installing cyanogenmod fix this?
