PaceyIV Posted December 12, 2015 Posted December 12, 2015 I've got a new problem with my Olimex A20 Lime2 board. The board doesn't freeze anymore (http://forum.armbian.com/index.php/topic/295-freezing-problem-with-olimex-a20-lime-2/) but after a week I've got a very slow speed using samba: about 300 kbps. I've tried to restart the smbd service but it doesn't work. The smbd process don't use cpu: < 5 %. If I restart completely the board, samba start to works again very fast and use the cpu: > 50%. How can I discover where is the problem and how to fix it? I'm using Debian jessie 4.2.6-sunxi, and there are no more updates.
tkaiser Posted December 12, 2015 Posted December 12, 2015 http://linux-sunxi.org/Sunxi_devices_as_NAS#Benchmarking_.2F_Identifying_bottlenecks "Always test from bottom to top" means: Use iperf to identify whether it's network related. 1
PaceyIV Posted December 21, 2015 Author Posted December 21, 2015 With dd and hdparm I can copy files very fast. I've tried to use iperf to test the network speed. Test1: server: Windows 10 client: OlimexA20 Bandwith 47.3 Mbits/sec Test2: server: OlimexA20 client Windows 10 Bandwith 4.97 MBits/sec What means???
tkaiser Posted December 21, 2015 Posted December 21, 2015 What means??? At least not related to Samba. Can you elaborate a bit on your network setup? Did you exchanged cabling and/or switch ports already? The performance numbers you posted are really low...
PaceyIV Posted December 21, 2015 Author Posted December 21, 2015 My OlimexA20 and my router have ethernet port with 1000 MBit/s but my notebook has only a 100 Mbit/s port. I've made the previous tests on wifi: the notebook was a meter far away from my router. If I use the ethernet port I've got a bandwidth of about 93 Mbit/s using Windows as a server for iperf and only 30/40 Mbit/s when I use Olimex as a server.
