I have two servers:
Server A - Windows 2019 Standard server with 64 GB of installed RAM. - D Drive with 1.26 TB memory
Server B - Windows 2022 Standard server with 200 GB of installed RAM. - D Drive with 2.5 TB memory
As a part of an agent job, I use azcopy to copy a .bak file (~90gb) from Server C to both Servers A and B. To copy to either server takes the same amount of time. To restore the backup on Server A takes roughly 40 minutes. On Server B the restore takes over 60 minutes consistently. The rest of the ETL on Server A is about 40 minutes faster than B, they are running the same job.
What might cause the difference in restore speed?
