How much memory do you have in your system? If the answer is 4G or less then there is no advantage. Stay with the 32-bit kernel. If the answer is 64G or more then yes you should definitely use a 64-bit kernel. If the answer is between 4G and 64G then the answer is "it depends" and there are advantages and disadvantages to both. If you currently have a 32-bit system then I recommend staying there. A 64-bit kernel won't have much advantage for a 32-bit userspace. It is rather a pain to change from 32-bit userland to 64-bit. Not really worth it. Is your web browser exceeding 3G of ram image? If the answer is yes then you should re-install to a 64-bit userland. If the answer is no then stick with 32-bits. > And if it is a good idea, how do I do it?

Simply install the linux-image-amd64 metapackage, let it drag in the version numbered kernel, and then reboot to it. # uname -a Linux joseki 3.2.0-4-686-pae #1 SMP Debian 3.2.65-1+deb7u2 i686 GNU/Linux # apt-get install linux-image-amd64 Reading package lists...
