Hi, We tried several combinations of configurations to figure out the cause for the delay we noticed in tenant creation. At the end, we found out that the cause is the registry mount. *Without* a registry mount, it took ~8 seconds for the tenant creation. *With* a registry mount, it took ~60 seconds.
When there were no registry mounts but when the primary user store was connected to an Oracle DB, it took ~30 seconds to create the tenant.
