Hi,

i hope this is the right place regarding my question..

I have problems with a Netjack connection between two Machines whenever, 
as it seems, a certain amount
of channels are being added and i cannot figure out the cause.

Machine 1 runs Ubuntu Eean and Ardour 5 on a I3-3210 with 4 GB RAM and a 
huge swap (just to avoid running out of memory)
Machine 2 runs W7 on a i5-4570, 8GB of RAM with Jack Netdriver (1.9.11)  
and a rather old Version of FL Studio, using Jack Netrouter as audio 
Device, unsing onboard Audio

Jack Netdriver on the Windows side is so configured that it offers 2 
capture channels and 32 Playback channels in Async mode.
Jack on the Server side (Ubuntu) runs in RT (also tried non-RT) 2048/2, 
44.1 KHz

Link between both is 1 GBit/sec. Afaik bow cards are idenitified as RTL8169.

First problem:
- transferring more than two audio channels simultaneously usually leds 
into "stutter" on Ardour.

Second Problem:
-transferring Audio over more than 10 Channels kills JackD immediate on 
the server side. Log is on the end of this mail.

Done an iperf(3) between both machines shows no sign of Packet loss (TCP 
and UDP), Transfer speed is about 903 GBit/sec. Ping is between 0.2 and 
0.3 msec

Tried with different MTU´s on both sides between 1500 and 9000, before i 
replaced my old Slave machine with the I3 it sometimes helped to switch 
between 1500-900-1500 while Playback of the Slave machine to get rid of 
the stutter.

I also recompiled JackD on the master machine from 1.9.12 to 1.9.14 with 
additional DBUS-support, but it doesn´t make any difference.

Firewalls are off while testing. also killed Pulseaudio.


Tried to turn off anything which has to do with Speedstepping, set with 
cpufreqd everything to "performance", no success at all. Even fillding 
around with sync, async, different Buffer sizes, periods- no chance.
Yes, according to the log i recognize the missing data packets, but have 
no clue what could be the cause - Jack itsef, the Jack Netdriver on the 
Windows side....



Before Ardour connects to Jackd, i also get a lot of 
"ProcessGrapMasterASync"-Errors....and sometimes in between.


Any help would be greatly appreciated, because i run out of ideas....

Best regards
Stef
