You may not judge exactly in Ideal.
It depends upon lot of verticals.
1. No of concurrent users accessing the application.
2. Depends upon the Memory of both Local & Server
3. Heap size.
4. Accessing from VDI or Local machine.
In an Ideal situation it should take more than 1.5 hour near by or even more in worse Scenarios.
My Queston.
Who would just bump this much of data @ one shot..??
Could have been split into folders and upload accordingly.
If application hangs, you would be in much trouble to check the same in the next login.
