A fork can both result in spurious notifications as well as in libev having to destroy and recreate the epoll object, which can take considerable time and thus should be avoided. +All this means that, in practise, C<EVBACKEND_SELECT> is as fast or faster +then epoll for maybe up to a hundred file descriptors. So sad. + While nominally embeddable in other event loops, this feature is broken in all kernel versions tested so far. |
