I'm not too surprised by that.  Each task is not doing much
work in between calls to Get, so the synchronization overhead
for the protected procedure calls will be high.  If you
split the work up into Num_Tasks pieces, I'd expect it
to be faster, because then the only synchronization overhead
would be in activating and terminating the tasks.

By the way, I don't see the point of the Create_Tasks block.
Seems like it's not needed.
