ProjectWise Web & Drive

I hava a gigantic catalog to sync. I press sync. Projectwise drive shows that the drive is syncing. How fast does it sinc? will it sync in 10 minutes, 1 hour, 2 days? what amount of bandwith does it take? will it ever sync? did it freeze or pause? what is happening? There is virtually no info and it is very limiting. I would not use it but I am forced by the client.
