Dear Alexander,
could you please also test a parallel job (just put 2, 4 and 8 lines in 
the klist file with the same kpoint and submit with the parallel option) 
in order to evaluate the how good is the memory band width.
A perfect system (without saturation of the memory band width) should 
give the same CPU time to calculate 1 k-point, whatever the number of 
parallel job submitted.
I am expecting rather bad performance for 4 and 8 parallel job on Xeon
 
Please could you please be more precise about the frequency of the CPU 
(1.86GHz->2.67GHz)
Best regards
Florent
