The threading model is still difficult, and it's still enough slower that thinking you're going to be comparable to custom silicon that's been designed for a particular protocol is silly.

It's great fun for doing signal analysis, but I'd never want to try and implement a full-duplex communication system in production with it.

If I were doing SDR-based comms in production, a custom C (or C++) application would be on the table, and nothing else.
