What can I expect for relative performance for each system, assuming that each one has, for example 64 MB memory? If this is an overpowered home system with only occasional periods of sustained computation, would I need more that 64 MB? For example, on a lightly loaded system, how much faster is the Pentium Pro? Which system (dual P5 vs. 1 P6) would be faster at compiling all of FreeBSD from scratch? Thanks.
