Hi Markus,

I can verify this on Windows Vista, Mathematica version 7.01.

Normally you Mathematica needs more memory because it stores output lines. 

However, setting $HistoryLength to zero does not help. Consider:



$HistoryLength = 0;

Do[

  ClearSystemCache[];

  ListVectorPlot[Table[{y, -x}, {x, -3, 3, 0.2}, {y, -3, 3, 0.2}]];

  Print[MemoryInUse[]];

  , {10}]
