There are pieces of the setup that might be causing this. Pulpito on its own doesn't do much, it is stateless and just serves HTML. I would look into paddles (pulpito feeds from it) and see how that is doing. Ideally, paddles would be setup with PostgreSQL as well, I remember that at some point the queries became very complex in paddles and some investigation was done to improve their speed. > > ubuntu@teuthology:~$ curl > http://localhost:8081/ubuntu-2015-07-19_15:57:13-rados-hammer---basic-openstack/ > > /dev/null % Total % Received % Xferd Average Speed Time Time > Time Current > Dload Upload Total Spent Left Speed > 100 391k 100 391k 0 0 42774 0 0:00:09 0:00:09 --:--:-- > 96305 > > Do you have an idea of the reason for this slowness ? > > Cheers > > -- > Loïc Dachary, Artisan Logiciel Libre > > -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
