("." "/var/lib/texmf/tex/" "/usr/share/texmf/tex/" 
"/usr/share/texlive/texmf-dist/tex/"

See above. Could this also be related to the location of the *.tex file? 
I mount some remote samba share via VPN to my file system and all the 
files Latex uses are located there. Maybe the change in speed that i 
noticed is not due to me updating my system but due to me changing my 
physical location. Before I worked at a place where these files were 
located in the local network and were not acessed over the internet.
