After using erpalma's python script...I'm not impressed with performance. I don't think it's all lenovo's fault.
I have a laptop from a few years back and without messing with anything it still compiles mesa faster than my x1 carbon with tweaks
12min without tweaks
10.5min with cpufreq set to performance
8.5min with erpalma's python
7min with a 4810mq (also 4core/8thread, -.- then they quit and made dual core for half a decade, why?)
i feel kinda robbed...

Hmmm... That's strange. On my T480s (8550u) with Gentoo:
media-libs/mesa-18.0.2 -> merge time: 2 minutes and 57 seconds.
This includes download + compile + install phases. I have almost the same performance of my desktop i7 6700 in multicore!

hm, what's your use flags/emerge -pv ?
(see that i'm using 17.3.9, 18 i think compiles faster so that's 1 thing. also use tmpfs for /var/tmp/portage)
