fwiw, I have a mixed ubuntu 11.10 / 12.04 6 node cluster (AWS m1.xlarge). The load average is always between 0 and 5 for 11.10 nodes while 12.04 nodes shows all the time a load between 2 and 20.
I have the same configuration on each node and the average request latency is a few better on 12.04 nodes (which have the higher load). htop shows about the same cpu used for any of these nodes so does iostat (same iowait, user, system...). I am not sure why this load increase, but I am not sure either that this is a problem.
