Pulpito on it= s 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 d= oing. Ideally, paddles would be setup with PostgreSQL as well, I remember that at some point the queries became ve= ry complex in paddles and some investigation was done to improve their speed. >=20 > 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 T= ime > Time Current > Dload Upload Total Spent Lef= t Speed > 100 391k 100 391k 0 0 42774 0 0:00:09 0:00:09 --:--= :-- > 96305 >=20 > Do you have an idea of the reason for this slowness ? >=20 > Cheers >=20 > -- > Lo=C3=AFc Dachary, Artisan Logiciel Libre >=20 >=20 -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
