Speed-- Restoring from Azure Blob to local database
You can also turn on Trace Flag 3051 when doing the restore to
  generate a detailed log. This log file is placed in the log directory,
  and is named using the format:
  BackupToUrl---action-.log. The log file
  includes information about each round trip to Azure Storage including
  timing that can be helpful in diagnosing the issue.

And you can also use AzCopy to download the backup to a local disk first.

Or overwrite a daily backup on a local disk in addition to the Azure backups.
