FWIW, we are seeing 2 x quad-core 2.66GHz outperform (per core) 2 x

bandwidth to memory. However, this is on a compute-intensive workload
running 1 job per core so would be pretty insensitive to
scheduler/locking issues.
Alexey's problem is pretty specific to filesystem performance.  Good to
hear though :)

If that is the conclusion, wouldn't it make sense trying a different
disk-controller then?

Filesystem, not disk.  See my earlier email for more detailed discussion.
