question?

[darkwizard864]

can lmce handle 48 ports on eth0?
if I take off 2 hdhomeruns no buffer issue with mythtv if 2 readded it buffers?

so I am thinking lmce can not handle all the load on eth0? eth0 runs e1000 gigbit Ethernet...dual card

What 48 ports are you talking about?

[darkwizard864]

48 port network switch by netgear

LinuxMCE can handle as much as your NIC card can handle.  HD HomeRun devices use <40mbit per channel.

It shouldn't cause an issue.

this is what I have on eth0 threw netgear 48 port port 1 lmce input port 2 camera 1 port 3 camera 2 port 4 camera 3 port 5 camera 4 port 6 bill pay pc port 7 nas 1 port 8 nas 2 port 9 nas 3 port 10 md port 11 gc 100 port 12 pioneer port 13 hdhomerun prime port 14 hdhomerun prime port 15 hd homerun prime port 16 hitachi projector port 17 threw 24 ip phones (polycom 303)


if I take off 2 hd homerun primes no prebuffer on mythtv
if I leave them on major buffering.

my core is a amd fx 8350 with 128 gb ram and 2 480 ssd hdds

Sounds like the issue is the HDHomeRuns.

I have seen this issue, myself, which leads me to believe that the HDHR needs either some segmentation, VLAN, and/or QoS action at the switch, as it tends to be very chatty.

The HDHR is very chatty, and it's all UDP streams, which can affect the switch buffers on inexpensive Ethernet switches.  As Thom said, if you have a layer 2 switch, putting it on it's own VLAN, or applying QoS are two possible options. I just put my HDHR on a dedicated non-routeable network adapter and switch, and configured MythTV to look for it on that segment.  It eliminated a lot of weird network issues (and I did that long before buying a Layer 2 switch).

HTH!
