Lenovo X1 Carbon 5th Gen. (X1C5) Fixes for Arch Linux
Almost everything of this awesome machine works out of the box. But, it is still bleeding edge hardware so not everything is already supported in the stable kernel. This list should help to fix the most annyoing problems, which are not much.
Download the latest BIOS version for your model, visit pcsupport.lenovo.com, enter your products serial number (e.g. 20HR-), goto Drivers&Utilies and download the BIOS.
I am not sure about the next step because Lenovo already provides a bootable CD image but I followed did run this instruction and the BIOS updated worked flawless, so here it is: geteltorito.pl -o converted.img n1mur10w.iso where n1mur10w.iso is the name of your bootable BIOS update image.

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
