I took a quick glance at the 2009
sortbenchmark.org results, where Hadoop reached the first place.
The benchmark category is called GraySort
Metric: Sort rate (TBs / minute) achieved while sorting a very large amount of data (currently 100 TB minimum).
This is how it looked like
73 times more nodes!? 
(the raw cpu power of the nodes are roughly comparable - both Dual Quadcore)
Even though the benchmarks themselves aren't 100% identical (but triton was also sorting 100 terabytes), I think its remarkable..
Sometimes you just have to look at the numbers.
