I am new to Linux. I am working on a speed up boot-time project. I am using Arch Linux on raspberry pi B+. I am particularly looking into netctl service. To trace down function time, I have edited some of scripts in /usr/lib/network. and I got to know that, it's slow hardware(?) and also stuck up in resolv.conf as it can't find /etc/resolv.conf.

code snippet for slow hardware(?) is given below.
if is_yes "${SkipNoCarrier:-no}"; then
SkipDAD=yes
else
# Some cards are plain slow to come up. Don't fail immediately.
if ! timeout_wait "${TimeoutCarrier:-5}" '(( $(< "/sys/class/net/$Interface/carrier") ))'; then
report_error "No connection found on interface '$Interface' (timeout)"

this is my ethernet profile

I am using static connection and I have disabled DHCP service and, as of now, I am not interested in IPv6.
What could be the solution to speed up boot time? Should I switch to systemd-networkd service?
