Well, I've had my MOI for about a week now, As supplied it's running a buildroot/ulibC userspace and a Kernel without NFS support or loadable module support, So i've rebuilt the kernel and installed Debian Wheezy to a SD card. I have it running a v0.26 slave backend from the debian-multimedia repo. 

I've currently got it recording to a NFS sever but the performance is questionable, it can manage a SD single recording, but seems to struggle with two. on Investigation it would appear to be network related, whilst recording two streams the kernel rpciod process uses around 60%CPU (mythbackend is around 35%) I've done some testing with IPERF and could't get it above 50mbits (where as my master backend to the same server hits 950mbits) so there is something wrong with it's network stack, but I'm not sure where to look.

Any ideas anyone or should I just right this off to experience?
