Is it supposed to take this long?

I usually bring up taskmanager (control+alt+delete on XP/NT systems)
select process tab, and right click on cmd.exe select priority, and set it to high(or realtime if your not doing anything but sourcing) also, do the same to mysql.exe right before you start sourcing your files. That will give those tasks more cpu time, and should help decrease the time.
