The test tries to bind configured nr. of PVs to the same nr. of PVCs. '100' is used by default, which should take ~1-3 seconds (depends on log level). Periodic sync is needed in rare cases, which may add another 10 seconds. - cache from #25881 will help here and sync should not be needed at all. The test is configurable and may be reused to measure binder performance. Set KUBE_INTEGRATION_PV_* env. variables as described in persistent_volume_test.go and run the tests: # compile $ cd test/integration $ godep go test -tags 'integration no-docker' -c # run the tests $ KUBE_INTEGRATION_PV_SYNC_PERIOD=10s KUBE_INTEGRATION_PV_OBJECTS=1000 time ./integration.test -test.run TestPersistentVolumeMultiPVsPVCs -v 2 Log level '2' is useful to get timestamps of various events like 'TestPersistentVolumeMultiPVsPVCs: start' and 'TestPersistentVolumeMultiPVsPVCs: claims are bound'.
