Do we have performance comparison between both implementation?

We are implementing qemu official vhost-user interface into DPDK vhost library, so there would be two coexisting implementations for user space vhost backend.
Pro and cons in my mind:
Pros: works with qemu version before 2.1; Cons: depends on eventfd proxy kernel module and extra maintenance effort Qemu vhost-user:
Pros: qemu official us-vhost interface; Cons: only available after qemu 2.1
