Hi there,
I’ve got Raspberry Pi3 with OSMC installed
Apple TimeCapsule 4th gen as wi-fi router and network share disk
Mounting Time Capsule disk via fstab:
//10.0.1.1/Data /mnt/tc cifs x-systemd.automount,noauto,user=admin,pass=********,rw,uid=1000,iocharset=utf8,sec=ntlm,noperm 0 0
As a result, I am getting extremely slow read and write speed to /mnt/tc
About 1 MB/sec
adding cache=loose option can increase up to 1.5 MB/sec, which is slow as well
Tried afpfs-ng. Reading is up to 3 MB/s, writing no more than 1 MB/s
Also tried to make another samba share from MacBook - same speeds, so Time Capsule doesn’t seems to be a bottle neck.
Measuring reading speed with
dd if=/mnt/tc/temp1 of=/dev/null bs=4k
If I measuring my internet connection speed with speedtest:
curl -s https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py | python
Download: 32.60 Mbit/s
Upload: 33.82 Mbit/s
So, networking in raspberry looking fine as well
Why there is such poor network share performance?
First off, please provide full logs.
I know little about the Time Capsule other than what I just found searching on the Internet. It might be that the poor network share performance is due to some compatibility issues between Debian’s and Apple’s implementations of SMB. Do you see such poor performance from the MacBook using SMB?
If you want, you can try an iperf3 test between the Pi3 and MacBook. If you see somewhere around 90 Mbits/sec, that will at least eliminate one factor.
What kind of logs do you like?
No, MacBook works perfectly with TC
Will try and post it here, thanks
Run grab-logs -A from the command line and let us know the URL.

You’ve run grab-logs -a. It needs a big A.
I think you need to try a wired connection between the Pi and the Time Capsule and see what the read/write performance is. I’d recommend you also switch off openvpn during the test.
Well…
I did fresh install of OSMC (just in case)
Wired RPi with TimeCapsule
Disabled openvpn
Read: 9 MB/sec
Write: 8 MB/sec
Guess thats the point. But its impossible to use this setup permanently: don’t want a cable across the room 
What do you think of external usb wi-fi dongles? Would it be better than internal wifi?
Actually, it is!
Connected old dongle and now I got around 5 MB/seс for reading
Funny thing the writing speed is 1-2 MB/seс faster (5-6 MB/sec)
Is it maximum, I could get using wifi and time capsule? I guess this is good enough for streaming 1080 videos…
Well next step would be a 5Ghz dongle
Thanks a lot for your help!
Would you didn’t state was the channel you were using on 2.4GHz wifi. There are only 13 channels and every router defaults to channel 1,6 or 11. Changing the channel to either 3,4 or 7,8 can make a huge difference. You can loose as much as 15% per adjacent channel.
5GHz has more channels but for same transmitting power you will only get half the range as 5GHz is more rapidly absorbed than 2.4GHz, however there are many more channels and adjacent channel interference is less of a problem.
