okay, thats quite different ...

a) you run the lowlatency kernel for whatever reason ... this is clearly
the worst choice you can pick for already slow hardware (low latency ->
do one thing as fast as you can ... ignore other things ... i.e. you
trade overall system performance for the ability to do one single task
very fast (a typical use for this kernel is fully reliable professional
audio processing (no crackling, no jitter) at the cost of desktop
performance)

b) the (third party) wlan driver crashes in a loop, preventing the
network from coming up for quite some time ...

c) you seem to run dnscrypt-proxy and that seems to effectively delay
working DNS resolution until the end of the boot for whatever reason ...

same question as before ... have you tired running a completely
unmodified install of 20.04.1 on this hardware ? did that behave
similarly slow ?
