I suppose we might consider discussing changing the default vm.swappiness value to something smaller, but I guess someone would have to do some testing and comparison so we have actual numbers on how it affects system performance. Not sure if I would consider it a hotfix for OTA-8.5 though, not enough research done on this.

It didn't seem to follow a particular pattern, but i could definitely tell it was effecting the ui (stalling) ogra indicated our swappiness should be very low. so i did sudo sysctl vm.swappiness=10 as instructed, however as i continued testing, i continued to see kswapd continue to run and peg the cpu at about the same frequency.
