It's very easy for classes with stealth, the 2 mini-bosses are complete pushovers, so it takes about 10 minutes, skipping all trash.
I'm soloing it weekly on my marauder, althought it takes a bit longer due to limited stealth.
In short, if you're an Operative/Assasin/Marauder, it's probably worth it to solo the quest, goes faster than looking for a group+clearing the whole place.
