I am an amateur, and so I don't have big libraries.
Just for the record, I am a professional (not of the machine-gun camp -- I use a camera to make limited edition fine art prints), I run large and huge Libraries, and they all work well. I know many amateurs who have large Libraries. They work well, too.
I regularly use a Library with over 3/4 million Images. SuperDuper tells me there are more than 8 M files in the Library, not including the Originals (they are all referenced). My system does not freeze.
Afaik, there is no known problem of Libraries freezing because of size.
Any Library that triggers a crash (or worse, a kernel panic) _is_ a big problem. Any application that is unreliable shouldn't be used. But IME and those of others I know, Aperture is currently stable. I have no problem recommending it to photographers, however they make their living.
More apropos to this thread: use what meets your needs. It's not complex. If Aperture 3.5 does not meet your needs, and something else does, use it.
