The heat seems to be a design issue - he mentions the bus being only 16 bits wide. I'd hate to think ARM chips don't scale up after all...
Here's performance numbers from a "SheevaPlug". Seems about half the power of an equivalent intel CPU, but its floating point performance is about 1/35 (like, really bad; no hardware FP). File serving isn't FP intensive though. Around about a "P3 800Mhz". http://computingplugs.com/index.php/SheevaPlug_Performance

The SheevaPlug was the predecessor of the GuruPlug http://en.wikipedia.org/wiki/SheevaPlug
