So any decent epoll implementation should let us hit that without a super optimised server - eventlet being in that category. I totally get that we're going to expect thundering herds, but websockets isn't new and the stacks we have - apache, eventlet - have been around long enough to adjust to the rather different scaling pattern. So - lets not panic, get a proof of concept up somewhere and then run an actual baseline test. If thats shockingly bad *then* lets panic. -Rob -- Robert Collins <rbtcoll...@hp.com> Distinguished Technologist HP Converged Cloud __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
