Had to change first the Language in English so I could understand it.

What did iperf? after Force refresh?

You run iperf from the ssh command line. You need it installed on two computers, ideally one at each "end" of your network segment being tested. One computer acts as the server, the other the client (doesn't really matter which is which), and iperf measures the raw network bandwidth available between those two computers.

iperf eliminates other variables such as filesystem overhead and disk IO which can negatively skew the network performance when testing using a file copy (most likely why your file copy test "fluctuates", as the CPU is busy writing data to SD card it can't service the network so quickly).

Perhaps this will help: http://openmaniak.com/iperf.php

Ow, haven't seen there is already a page 2, sorry.

When i push "O" the on screen appear this.

By P(aq:40% , KB/s should that be kB/s and is this the bitrate?

Milhouse, thanks, I'm going to read.

How do I run iperf with Putty /ssh commandline?
I found iperf for Windows on a France site.
https://iperf.fr/

and witch is to prefer as server? Mu Windows PC or the rasp?

Your tests (40.3 Mbits/sec and 44.1 Mbits/sec) look normal for a non-overclocked (or very lightly overclocked) Pi, these are my results:

A high-bit rate Blueray may be too much for a Pi with default or low overclock settings, so try overclocking more (see if you can reach arm_freq=1000 - bump over_voltage if necessary for a stable overclock, see other threads to continue overclock discussion).

Monitoring with bcmstat.sh could help determine if the buffering coincides with large network transfers, which may suggest the lack of network capacity (due to low overclock) is the problem.

PeterBoomhut · 2015-01-08, 19:03

Overclock settings:
- ARM frequency (arm.freq) = 1000
- Core frequency (corefreq) = 500
- SDRAM frequency (sdram_freq) = 500
- ARM voltage adjustment (over_voltage) = 6
- SDRAM voltage adjustment (over_voltage_sdram) = 0

I can try to overclock more, but i dont't think it will help.

The same overclock settings but directly from asus RT n66u (thus without the switch)

That is a great difference !
But still stuttering because of an empty buffer

Can you perhaps explain what was happening while the above stats were being collected?

I can see the Pi is busy doing something, most likely decoding a video since the h264 block is active, but there is very little network activity, at least not on eth0. Considering the lack of network activity, the one thing that does stand out is the higher than usual IRQ/s - what devices do you have connected to USB? You don't have a WiFi dongle connected, do you?

Please run "dmesg | pastebinit", "ifconfig | pastebinit", and "lsusb | pastebinit", then reply with the three urls.

The only thing that was active , is kodi itself. No playback!
On the usb is active :
1- A Microsoft wireless keyboard with touch-pad : ( I think it curse)
Key board

2- a transcend usb 3 memory stick

- "dmesg | pastebinit":
http://sprunge.us/LULU

- "ifconfig | pastebinit" :
http://sprunge.us/jDYg

Can somebody explain what the items displayed such as %user %nice in ./bcmstat.sh cxgd10

- lsusb | pastebinit
http://sprunge.us/PTMI

If that's the Pi "idle", then there's something very wrong.

These are a high-level(ish) breakdown of what your CPU is doing and where it is spending it's "time":

Code:
user  : time running un-niced user processes

nice  : time running niced user processes

system: time running kernel processes

iowait: time waiting for I/O completion

irq   : time spent servicing hardware interrupts

s/irq : time spent servicing software interrupts

idle and total are self explanatory.

So in your case, even though Kodi is apparently idle and not doing anything, you still have a user process that is keeping the processor busy and stealing cycles from other processes which would explain why Kodi is stuttering, as there simply isn't enough CPU to go around.

First thing I'd do is remove the keyboard dongle, reboot, and see if the load is now reduced. If not, put it back and continue with the next test...

Run the "top" command from ssh and see which process is using all the CPU. If it's Kodi (kodi.bin) then it's likely to be an addon that has gone haywire, or is poorly written. Start with a fresh .kodi setup:

Code:
systemctl stop kodi

mv .kodi .kodi.bak

systemctl start kodi

and see if the load is now reduced - a well-behaved Kodi process on a 1GHz Pi should load the CPU no more than 15-20% total (ie. 80-85% idle).

Add back your addons until the CPU load goes through the roof, and that last addon is your problem.

If top suggests some process other than Kodi is using all the CPU, then paste details of the process (copy the "top" output from your console, the first 12 lines should be sufficient).

i'll take another Top , after 5 minutes

Milhouse · 2015-01-10, 04:13

Bear in mind that Kodi normally takes a couple of minutes to initialise, so wait a good 5 minutes before measuring with top. If kodi.bin is still using more than 20% CPU constantly, then try the fresh setup route and re-apply your add-ons until you find the problem.
