SQL Log shipping - Very Slow restore I have SQL Server 2012 SP4, ten databases and log shipping.

One database 2.7TB


Ten data files and two log files


Log shipping configuration:


Transaction log backup job : 3 Min 
Copy job : 1 Min 
Restore job : 1 Min
Standby Mode, clicked Disconnect users...


A 50MB trn file take at 2 hours restored. The database is being 100% restored and remains. How do i solve this?
I added sql service account to Perform volume maintenance tasks and disk slowness problem appeared on the server. The storage team replaced the disks with faster disks. Problem is solved.
