i am running the 32bit version of lenny.
would there be benefits to use 64bit lenny instead?
in the archives, i found posts suggesting there is no benefit unless
you are using 64-bit apps that require extra processing power like
number-crunching.
64-bit is the future. Everyone will run it eventually. Except older
computers and possibly embedded processors, such the ones that power
.mp3 players and the like. ARM, Coldfire, SH-1, and so on.
Right now, there is no hurry to move from 32- to 64-bit, especially if
your machine has 4 GB or less. Or you need the 64-bit architechture
itself, for the extra registers, whatnot. Some number-crunching
applications can benefit from it.
A downside is 64-bits not only allows more memory, it requires it.
64-bit pointers vs. 32-bit pointers. Excuse me, *addresses*.
I recommend 64-bits for new installs, but for existing setups, there is
no need to update, unless you have specific needs.
