I have installed Firebird 3.0.2 SQL database on my Windows Server 2016. No other software has been installed yet.
I'm using Superserver mode and an SSD drive.
When I just copy my database file of size 6 GB, it is done in 20-30 seconds (same disk).
But when I execute backup it takes 20-30 minutes. Restore is about the same amount of time. Together 40-60 minutes.
And there is strange thing: backup/restore process (gbak.exe) does not use full power of CPUs and HDD. It is using only ~20% . I don't understand why.
I think it should be something in configuration right? But I kept everything in default values.
Very important thing: I am new in Windows Server 2016 so I have no idea what I am doing.
Any ideas?
I found out that it is about configuration of Power Options.
Windows Server 2016 is after installation set for Balanced Power Plan.
I changed it to High performance and results are highly better. (backup drops from 30 minutes to 6 minutes)
