Comment # 157 on bug 1112824 from Bruno Friedmann

Invited to join as a non impacted users :-) 

I share some informations :
I'm using plasma5 with xorg and proprio nvidia drivers
I didn't find or perceive any slowdown on my desktop in the last months.

I've tested geekbench and the result are there with a plain normal TW (up to
date)
https://browser.geekbench.com/v4/cpu/12014162

What I always apply is patch all hardware firmware for all component on my
hardware some have direct relation with spectre/meldown and as my cpu is a xeon
it is also preboot patched with kernel-firmware when the lastest Dell bios
doesn't contain all fixes.
