Very very slow startup WebUI RuneAudio

[votya4ok]

Hello.
I have installed RuneAudio_rpi2_rp3_0.4-beta_20160321_2GB.img.gz on my RPI 2. All's good, but webUI (RuneUI) is very slow startup - after 95 seconds!

Code: Select all

# systemd-analyze
Startup finished in 4.444s (kernel) + 1min 31.333s (userspace) = 1min 35.778s

I made graph.svf (at attachmnet).
What's wrong?

My hardware: Raspberry Pi2, MicroSD Sandisk ExtremePro 8GB, wired static connection. USB DAC and USB HDD with music not connected now.

Also i tried Volumio and Moodaudio - all two startup after 20-25 seconds.

My Debug info:

It seems that I has found a solution at this forum (Thanks to Frank).
I do not have wi-fi dongle, only a wired network.
Need to do:

Code: Select all

systemctl disable netctl-auto@wlan0

and reboot.

And now i have:

Code: Select all

# systemd-analyze
Startup finished in 3.746s (kernel) + 3.767s (userspace) = 7.513s

Excellent!

Hello! I just updated to the latest beta and am trying to get things set up properly.

I am also having very very slow startup, and then also very slow interactive use on the WebUI (as in, clicking around is extremely slow).

Any help would be extremely welcome! (I also am only using the wired interface, not wireless).

Code: Select all

root@rune(rw):~# systemd-analyze
Startup finished in 4.762s (kernel) + 1min 30.798s (userspace) = 1min 35.560s


Here is my debug info:

Then, looking in my journalctl output, looks like a lot of seconds are wasted in this area:

Ok, I believe I've solved my own problem. I did:

Code: Select all

systemctl disable netctl-auto@wlan0.service
systemctl disable netctl-ifplugd@eth1.service
reboot


and so

Code: Select all

root@rune(rw):~# systemd-analyze
Startup finished in 4.210s (kernel) + 4.329s (userspace) = 8.540s


In the interest of "teaching a man to fish", can someone explain what the problem was here and why this solved it?

Hi adamk,

In the interest of "teaching a man to fish", can someone explain what the problem was here and why this solved it?

Networking is done with "netctl service" and "services" are controlled by systemd on RuneAudio.

Rune tries to start the network as soon as possible, to get quick start-up.
If you do not have a wifi dongle installed Rune is paused until the service times out.
To disable the service you have to run this command once.

Code: Select all

systemctl disable netctl-auto@wlan0.service

Code: Select all

systemctl disable netctl-ifplugd@eth1.service

The same for the second ethernet port.
This command should be needless because it is not available and is not enabled on the Pi.

BTW: wlan0 should be disabled by default and only gets enabled when you plug in a wifi dongle.
