Szabolcs,
on my system and Mathematica 6.0.1 your original example takes 54.2s
to complete:

data = Table[{Random[], Random[]}, {100000}];
Graphics[{PointSize[0.002], Point /@ data}, AspectRatio -> Automatic]

The following equivalent statement (not available in Mathematica 5.2)
takes 0.173s:

data = Table[{Random[], Random[]}, {100000}];
Graphics[{PointSize[0.002], Point[data]}, AspectRatio -> Automatic]

The version 5.2 graphics takes 1.58s to complete:

<< Version5`Graphics`
data = Table[{Random[], Random[]}, {100000}];
Graphics[{PointSize[0.002], Point /@ data}, AspectRatio ->
Automatic] // Show

In[69]:= $Version
Out[69]= "6.0 for Microsoft Windows (32-bit) (June 19, 2007)"
