OL7.3 performance degradation with UEK4 kernel

niksajurJul 18 2017 — edited Aug 4 2017

Hello,

has anyone running Oracle Linux 7.3 experienced  a performance degradation using the most recent kernel-uek-4.1.12-94.3.9?


So far I used to run UEK3 or regular RHK-3.10 kernels with no performance issues. Yesterday decided to download UEK4 and that was the first time I tried it. Performance degradation is more than obvious, especially when it comes to desktop graphics. Applications start two times slower, moving of mouse arrow sticks continuously (sometime the arrow freezes a few seconds), list boxes scrolling is ten times slower, browsing with Firefox is frustrating so the browser is almost useless.


Any idea what's wrong with UEK4 kernel?
