I'm a similar user by the sounds of it. Last night 2-3 shows downloads no problems, in fact they uploaded the same amount which is not the norm. I gave up using azereus ages ago because of a similar problem, nothing was finishing. I use utorrent now, find it great plus the scheduler helps manage the peak time.
So many variables to speed, you need to do a little testing before blaming the PN shaping, although I'm not saying it isn't that ! the new capacity can't come soon enough
