Matt Ryan commented on OAK-9488: -------------------------------- I'm assuming the slowness is around the creation of the NodeStoreFixture [0]: {noformat} NodeStoreFixture fixture = NodeStoreFixtureProvider.create(opts); closer.register(fixture); {noformat} I'll add some logging around that and a few other places to try to give a better opportunity to narrow down where the slowness is occurring. Assuming it is inside the NodeStoreFixture, however, to get more information will require changes down in that layer.
