I guess that's why I like puzzles being targeted to the second milestone in the cycle... deferring those is painful. > Without this patch swift will be a bottleneck running at ~17 MB/s while > the other parts can potentially reach ~100 MB/s. > > Risk: Currently the patch sets compression to be disabled by default > (giving better performance), but the old behaviour can be reverted > by setting the relevant config parameter.

At this stage of the cycle, I would definitely consider defaulting to the old behavior for Havana, and then this exception would be a no-brainer. With the proposed default, I have to ask how much mileage the "SSL without compression" swift mode has seen, and the risk is substantially higher. > The patch was originally uploaded on Jun 13. Yes, but it was WIP-ed for two months waiting for the necessary support to land in Swift... -- Thierry Carrez (ttx) _______________________________________________ OpenStack-dev mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
