actually i dont want to report it.
i evaluated "the irc opinion" and came to the conclusion:
- most people think udp is evil ;)
- it looks like i am the only one messing with BIG (16k) udp packets in
low latency situations under high SCHED_FIFO load.
i am currently implementing packet fragmentation into netjack.
if that improves the situation drastically i would start reporting on
this. in fact i am pretty annoyed by the kernel.
i would be very happy, if somebody (sletz ?) could test the performance
of 24ch connections under OSX.
and i dont have an rt-kernel on the second machine so i cant verify if
its already fixed in rt-preempt. Perhaps we need some kind of rt-network
packet.
/me hides.
Work is underway in improving the latency for big channel counts,
like 24in / 24out. There seems to be a bottleneck in the kernels
handling of big UDP Packets.
Nice, I'm looking forward to the LKML thread!
(you do plan to report it right...?)
not really :/
