You must have done benchmarks with very low numbers of precision, which 
is really boring and for which Mathematica is overkill.  If you are 
interested in numerical computations that require arbitrary precision, 
then Mathematica (I have to admit) is seriously good:
Note how, for all the 'easy' problems, it beats every competitor 
hands-down.  And how they did not even given entries for any of the 
'hard' ones!
