You hit the nail on the head: oscilloscope isn't the right app to get maximum radio throughput. It only runs once every 125 ms -- and, in addition to sending a message, gets data via the ADC from the photo sensor. 

Since most of our sample apps do something in addition to sending messages, just hack up your own. The meat of it might be:

event result_t Send.sendDone(TOS_MsgPtr msg) {
     call send(toAddr, sizeof(struct myMsg), msg);
