I have two NICs on a RHEL 6 server. They are both set at 1GB/sec full duplex. The first NIC has lots of small (< 100 byte) TCP socket writes. The second NIC is used to receive a 50 MB/sec TCP input stream where latency is critical.

In this setup, will the first NIC adversely impact the latency on the second NIC?
