The Centos runs with the default values. 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. > > Thanks ahead, > J=E1nos 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. -- Itai Seggev Mathematica Algorithms R&D 217-398-0700
