Hi Sam, We're just starting to look at v2.
We did see some really slow listing behaviour, backporting Ie7458044edbe1ef64871bcf5ef4996ed3cc0f957 helped a lot -- but you'll probably have that change already if you're using more recent code. Even with that it does seem slower in some cases, eg devstack listing 1000 images: v1: $ time ./.tox/py27/bin/glance --os-image-api-version 1 image-list > /dev/null real 0m6.058s user 0m1.348s sys 0m0.172s v2, no registry: $ time ./.tox/py27/bin/glance --os-image-api-version 2 image-list > /dev/null real 0m15.487s user 0m9.233s sys 0m0.120s v2, with registry: $ time glance --os-image-api-version 2 image-list > /tmp/out real 0m21.904s user 0m9.217s sys 0m0.116s -Stuart On Wed, 25 Jun 2014, Sam Morrison wrote:
We’ve recently enabled glance v2 API on our glance servers. We’ve noticed it is considerably slower than v1 to do things like glance image-list. (~4 seconds compared to ~1) Has anyone else experienced this or run any benchmarks comparing the two APIs? I should note we’re using glance registry for both v1 and v2 requests too. Also just wondering if people are actually using v2? For instance from what I can tell you can’t create an image with v2 via the client yet [1] Cheers, Sam [1] https://bugs.launchpad.net/python-glanceclient/+bug/1302351 _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
