[ovs-discuss] 答复： OVS mirror performance problem?

[lifuqiong]

There are two famous companies are using OVS in my private cloud enviroment, one of them don't allow us making mirror using select-all option, and VMs over ovs will drop package sharply when flow is more than 600 KBPS;the other company just allow almost 4 mirror source ports to an output port, and told us the affordable mirror flow is 400 MBPS,  but my common business flow can up to 10GBPS;They didn't tell me the reason cause the mirror performance, could you give me some advisor?

In any version OVS is ok, thank you.There shouldn't be much impact on performance.  It's just copying the packet out an additional port.--Justin
