Following the outbreak of KPTI news, I recently updated my kernel to 4.14.11-300. In addition to a quite sufficient RAM (8 GB) and fast IO (SSD disk), I have started to feel remarkable slowdown in my system performance when I am mulitasking for example editing code orand perform some other not-so-resource-intensive jobs, especially when I run out of physical RAM and switch to swap, which is hosted on SSD disk. I read in article, that you can disable the new imposed performance hit using the nopti option. I did not find any command on my Fedora 26 as nopti. Where should I use this feature and how?
