We have plans in place to improve clustering performance and to construct tests to validate and 16:13:59 measure those improvements in the next release. 16:14:35 #info (cont) ...measure those improvements in the next release. 16:15:07 * dfarrell07 got dropped 16:16:01 #info Discussion about groups we know are using clustering, that it works okay when not pushing it hard for perf testing it seems 16:16:29 A change was merged to integration/test: Add Boron perf report stub https://git.opendaylight.org/gerrit/45714 16:16:39 dfarrell07: merged the stub. https://git.opendaylight.org/gerrit/#/c/45714/ 16:16:52 #link https://git.opendaylight.org/gerrit/#/c/45714/ <--- patch with perf report stub 16:16:52 jamoluhrsen: thanks :) 16:20:31 #endmeeting
