The SETI@home data recorder on the Arecibo radio telescope records 256 work units every 100 seconds, or 154 work units per minute (WU/min), whenever it is enabled. Actually, it records a continuous signal, which the splitters divide into 100-second segments plus overlap, and into 256 subbands. Each of the splitters at Berkeley takes about 234 minutes to chop 100 seconds of signal into 256 work units, producing about 1 WU/min, and there are currently 9 splitters. It then takes the average client machine 7 CPU-hours to process the WU, but there are so many clients running in the world that the total capacity is 1026 WU/min. This enough to keep up with 6.7 full-time data recorders, but only if there were about 939 full-time splitter machines instead of nine.
