i believe barracuda uses spamassassin. barracuda is pretty much a

It's one of ten programs it uses for filtering and likely highly
customized. The main advantage to running a Barracuda is that it's
dedicated hardware. I have never seen load averages on Linux servers in
production like the ones I've seen on Qmail Toasters and it's
predominantly because of the burden of spam filtering. Again, for a few
users it's fine, but if you're, say, an ISP with thousands of users,
it's unscalable and a Barracuda ends up being a much more elegant
solution.
It's all in how you configure it. I run single servers with over a
thousand users using spamassassin.
I've also set up servers for ISP's with multiple thousands of users in a
scalable array/cluster, still using spamassassin. In this setup you can
drop another machine into the mix in about 10 minutes and it
automatically begins to take some of the loads from the rest, spreading
it evenly (somewhat) between all the machines.
Is Qmailtoaster set up for ISPs out of the box? Nope.
Can it be set up for ISPs? Yep.
