First call for reports of slow boot time is this post.
It includes advice on disabling startup services and fixing IP addresses to trim a little time.

A command suggested in that post is
Code: [Select]
systemd-analyze critical-chain

Hallo! Das dauert bei mir ca. 1min. 40sek., es ist doch kein Lichtschalter.  Der Speicher kann vielleicht um 4GB verdoppelt werden. Beste Gre, K.H.

My linux lite is taking a while to boot. Can I make it faster?

My pc specifications:

This is the systemd-analyze time output:

Sometimes the networking.service is taking almost 20sec.
I wanted it to boot faster, what can I do?
