We should add this one to the list: https://www.dpdk.org/ecosystem/#projects Also a discussion has started recently about integrating one in DPDK. As Jerin suggests, libtpa looks like a very good candidate to focus efforts on it. Regarding performance, how does it compare with F-Stack? TLDK? Seastar?
