Hi Lukas, starting from around 200mbit/s in&out, haproxy processes (nbproc 6) are hitting 100% cpu regularly (noticed up to 3 processes at the same time with 100%), but recover again on its own after some time.
stracing such a process yesterday showed the following: epoll_wait(0, {}, 200, 0) = 0 epoll_wait(0, {}, 200, 0) = 0 epoll_wait(0, {}, 200, 0) = 0 epoll_wait(0, {}, 200, 0) = 0 epoll_wait(0, {}, 200, 0) = 0 Unfortunately I can't do any more debugging in this setup. HAproxy 1.5.14 is never near to 10% cpu usage with way higher bandwidth.
