There are factors:

1 - Like poor Wifi connection

2 - Slow wifi connection

3 - Too many other people downloading at the same time and Apple Severs are overloaded

4 - Software on the computer interfering with the download process including AntiVirus Software

5 - Running behind a VPN which may increase Packet losses and may corrupt the download

6 - If via wifi too many Other devices using the wifi at the same time reducing the Bandwidth to your computer.

7 - Best Results are via Ethernet Cable to Router
