I think part of what Klaus K is saying is that for many/most Linux 'ordinary' Knoppix
users, using 64-bit applications won't show MUCH, if any performance improvement over
using the same 32-bit application. Think spread-sheet, browser, word-processor, etc.

I don't think there should necessarily be ANY performance penalty in using 32-bit
applications with a 64-bit kernel enabled.
