Thanks Frank and everyone else who replied.

Ver.5.2 is still considerably faster than 6.0.1 in this respect, even 
after setting the PerformanceGoal to speed.
It took 12 secs to show a 500x500 density plot in 6.0.1 and less than 
0.3 secs in 5.2.

T = Table[N[Sin[i/50] Cos[j/50]], {i, 1, 500}, {j, 1, 500}];

SetOptions[ListDensityPlot,PerformanceGoal->"Speed",MaxPlotPoints->\
Infinity,ColorFunction->GrayLevel];

Timing[ListDensityPlot[T,Mesh->False]]

ArrayPlot is fast but the result looks different.
