It isn't true that 64bit applications are slower than 32bit ones. It
really depends on what the application does.
The main reasons to use a 64bit application are:
1) You need a large address space - possibly via mmap()
2) You need to control (via /proc) another 64bit process
3) You want to take advantage of the performance increase that can be
had from 64bit - this is more relevant to AMD64 than to SPARC.
It really really depends on the application wither a simple recompile
will result in better or worse performance between 32 and 64 bit. Some
applications aren't even 64 bit clean so won't work properly in 64 bit mode.
I wouldn't expect to see a 64bit vim binary.
