MapReduce scalability

Hello,

I'm experimenting with 2 Riak 1.3.0 nodes (both are "bare metal"), and it
looks like mapreduce performs better when one of the nodes is down. The
mapreduce requests are running on 20-key blocks. So am I doing something
wrong, or is it an expected behaviour, i.e. mapreduce degrades with the the
number of nodes increased? If the former, could
you give me some pointers on how to set up it to get advantage of multiple
nodes?

Thanks in advance for your help,
Boris
