PNG compression level 6 or 9 ?

When saving PNGs gimp defaults to compression level 6. Is there any reason why I should not use compression level 9 ... Is there a reason why this is not the default ?

I understand that the higher the compression the longer it takes to compress/decompress. So a file compressed more will download faster, but it would take longer to if you were to open them up on a viewer.

I could be wrong though.

This is what I thought, though my (pre-historic) 700MHz PIII, de-compresses in a trice ...
Many thanks
