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.
