Hi, I am facing issue with performance of 10 Gigabit Ethernet.
Environment 2 hosts each: - 2 * Intel(R) Xeon(R) CPU E5-2690 v2 - Intel 82599ES 10Gb Ethernet - 128GB RAM System: - Centos 6.5 delivered by fuel 6.0 iperf during test of network performance over single stream report 2,5-3Gbps (when using 4+ connection, cumulative transfer can hit over 9Gbps) For comparison, same test was run on official Centos 6.5 with result at minimum 9,3 Gbps In both cases default MTU 1500 was set. >From my analyses it looks like something is limiting i/o performance per stream. Are you aware of this issue, and can you comment on it? This is critical for our deployment.
