Currently I am capturing network packets using tcpreplay at a speed of 800 MBPS but I want to scale it over 5 GBPS.
I am running Joy on a server with 16GB Ram and 8 Cores
Tcpreplay Output:
`Actual: 2427978 packets (2098973496 bytes) sent in 20.98 seconds
Rated: 100003501.6 Bps, 800.02 Mbps, 115678.59 pps
Flows: 49979 flows, 2381.11 fps, 2426216 flow packets, 1756 non-flow
Statistics for network device: vth0
Successful packets: 2427978
Failed packets: 0
Truncated packets: 0
Retried packets (ENOBUFS): 0
Retried packets (EAGAIN): 0`
Total Packets Captured: 2412876
I am running Joy on 4 threads but even if I use 24 threads I am not able to see any drastic change in the capturing or receiving speed.
Joy is using af_packet with Zero Copy Ring Buffer and even Cisco mercury use the same mechanism to write packets but they claim that Mercury can write at 40 GBPS on a server-class hardware so anyone have any suggestion on this issue then please revert back.
