Heh. Guite the opposite. On the laptop typing this text I managed to gain performance by changing to pure 32 bit system code with 64 bit kernel about a year ago. The laptop is equipped with 1G RAM. With pure 64 bit the system had frequent swap storms and hitting 1G RAM usage while keeping my basic set of programs open on Xfce desktop. With 32 bit system memory usage got under 512 meg. The change was made plain and simple: got tired to lock ups, managed to monitor, what was the cause while system was nearly or totally unresponsive (kswapd, RAM usage and usually occured when switching between applications), and finally system reinstall with 32 bit binaries. After reinstall RAM usage with normal apps loaded showed 470 megs and I've been happy user since although I have pure 64 bit systems, but their minimum RAM is 2 Gigs. .
