It's likely to be a bit of a toy without that. Also, UDP?
The current patchset covers poll/select for UDP. Adding poll/select for TCP should be simple, I will try to include it in the next version.
Epoll should see a gain from the above in the case where all the polled file descriptors are associated to the same device queue. A fuller implementation, in the epoll itself would be needed to cover multiple queues/devices.
