Would like to know some numbers, especially PPS, using TAP = device and TAP PMD combo to fetch packets to DPDK application. Wondering do= those numbers change as Hypervisor platforms change? Assuming the resource= s (vCpu & memory) are unchanged across platforms. Mainly interested in PPS = measured on ESXi/KVM/Hyper-V platforms. I have never run TAP PMD in ESXi/KVM/Hyper-V so I do not know the numbers. = The performance of the DPDK TAP PMD is not going to be much better then any= other design using tun/tap as the kernel is still involved in the movement= of data. The TAP PMD was created to allow me to test applications with DPDK on a sys= tem without real NICs like my MACBook Pro I have a port of DPDK for a MAC. = The TAP interface should only be used for testing or if you need connectivi= ty to the host/another TAP device. With Pktgen I use it to connect to wires= hark to decode packets. >=20 > Appreciate the share if anyone might possess test results. >=20 > Thanks >=20 > Great day > --GG Regards, Keith
