The new Raspberry Pi 2 Model B can be ordered and it has vastly superior performance (~6x CPU and 2x RAM (B+)) compared to the first version. I always found that it is a problem that the ethernet port is connected through USB on the RPi 1. I have found it very slow to send/receive data to/from the RPi.
Is this also the case for RPi 2? The data sheet from a distributor doesn't seem to indicate either way.
