If you were writing naive code, it probably wouldn't be that much. Maybe a 2to 3 times difference. But the thing with Terra is that you can be even faster than naively-written C if you know what you are doing.
I am trying to explore Terra more for this reason, but Pallene has piqued my interest. My guess from the responses and what the authors of Pallene have stated is that Terra is probably better to stick with for numerical work.
