Hi,
I'm new to Apline and just installed Apline 3.5.2 to hard disk (in
Virtualbox, x86_64) with default options. During the boot, I note that
chronyd takes ~5 seconds to start, which I think is too much. How can I
improve this?
Wireshark shows that there are 3~4 NTP requests sent during the boot
with a interval ~2s, I think this explains why chronyd takes so much
time to start. But why can't it do this in background?
I try to start chronyd in command line, it also takes >5s before going
to background:
# rc-service chronyd stop
* Stopping chronyd ...
# time chronyd
real 0m 7.37s
user 0m 0.00s
sys 0m 0.00s
However I failed to find an option for command line or configure file to
change this behavior.
Regards,
Duan, Yao

I noticed this with chronyd too - now I use sntpc with:
SNTPC_INTERVAL="21600"
set in /etc/conf.d/sntpc

Great to know sntp.
I also found that I can workaround this issue by add `--background`
option to `start-stop-daemon` in `/etc/init.d/chronyd`.
However don't know whether this breaks anything.

Re: Re: [alpine-devel] Chronyd blocks boot for ~5s. How can I improve this?
I didn't notice slowdown with chronyd as I had enable rc_parallel.
But I did notice that I have to wait for tor to finish starting up which took
some time and as well it is the last service to be started on boot.
By the way duan yao, do you use IME in alpine?

Really? I tried rc_parallel but it made little difference for me. Maybe
because chronyd is the slowest one in my system.

What does IME stand for here? If it's Input Method, no.
