Based on my experience, AMP is the fastest and then Pb, fullscap is the
last one. I suggest using Pb first.. it is very nice and the performance
isn't bad. (At my machine, It can handle 5K req/s, 2K req/s for foolscap)..

I am not an expert on foolscap and I believe there are rooms for
improvement, moreover, foolscap provides more features in terms of security.
