Any good hint how to kick it into higher speed.  For example a calculation on my MacBookPro takes 26 second.  The same on the CentOS machine takes 38 seconds.

Without knowing specific hardware (exact cpu model, etc) and the computation
involved, this is impossible to answer, assuming this even represent an actual
problem.  Many Xeon processors have lower peak frequencies than their consumer
variants, for efficiency and/or price reasons.  Also, if you have a MacBookPro
with a Haswell processor, it is necessarily a generation newer than any dual
processor Xeon.  If your computation is essentially single thread (very
common), than your laptop may very well be faster than your workstation.
