Do you have any persisted namespaces with
If so, these namespaces can take longer to load since they have to load the data into RAM. We have made this a bit faster with “Cool Restart” but it is still slower than a “Fast Restart” of a persistence only namespace. Both “Cool” and “Fast” restarts require that the shared memory index is available (i.e. a clean shutdown and the machine hasn’t been rebooted.)
If you have rebooted the machines then they will need to “Cold Restart” which must rebuild the primary index from disk and if data-in-memory, load the data into memory.
If neither of these apply, could you share your configuration? You may want to reach out to your enterprise support contact to ensure a timely response.
