I don't see a problem here.
It sounds like you just have high-bandwidth streams:

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
