benchmarking 6.4 vs 5.02.3

I wrote about  ghc-5.02.1  taking 13 times less memory than 
ghc-6.4  to compute a certain example like merge-sort.

Now, I compare  ghc-5.02.3  and  ghc-6.4  on the same machine.

The needed time and memory occur the same all right.
The resources grow almost as O(n*log(n)), as expected.

My error was that it was  -H  used for 5.03 instead of  -M. 
With -M, they need the same time and space.

Sorry for confusion.
