All,
I am trying to check performance with vmxnet3 DPDK driver in the guest hosted on ESXi 6.5 hypervisor. What I observe is, for a target of 10G performance, the vswitch on ESXi host is becoming bottleneck. Just wanted to check two things.
(1) Are there any benchmark performance numbers for the above deployment (VMXNET3 DPDK in guest with ESXi 6.5 on host for Intel 82599 10G adapter on host).
(2) What are the known bottlenecks and are there any performance fine tuning techniques we need to follow. Please note that the promiscuous mode was identified as one of the overhead and it is disabled during the tests and observed some improvement (roughly 1Gbps to 2Gbps for 1518 Byte packets).
Please let me know if more information is required for answering the questions. Thanks in advance.
