downgraded to 3.2 original 12.04 kernel; using your sysconf values and
the issue occurred again in liveTV; another 20+ seconds lock in the
ringbuffer trying to read the data.
iperf on the dedicated internel link ; I get 993Mbit/s between the
backend machine and the NFS server.
Using dd if=/dev/zero of=/path/to/nfs bs=4k count=1M; I get 104MB/s
Using a little unit test with 4 simultaneous TFW; I get 75MB/s on that drive...
I don't see how their could be a bottleneck occurring watching a
single 12Mbit/s DVB-T stream...
