I don't see a problem here.

It sounds like you just have high-bandwidth streams:

>20 FPS and 32KB framesize)

That's almost 82 Mbps.  Are you sure you have sufficient network 
capacity for this (i.e., you don't just have 100 Mbps Ethernet, which 
would not be sufficient)?

If your problem is packet loss (but you have sufficient network 
capacity), then you need to increase your OS's buffer size for 
incoming network packets.  See
