Something like a Pentium NNN running Linux (I vote for NNN == 133, since that's what I happen to have, but maybe it would be better to use something a bit faster). The problem with Intel's machines is that they are not standard, but differ, even a lot, because of the bus architecture, cache, memory speed and so on. For example, the benchmark (octave 1.1.1) results list 2.0 as the performance for a Pentium 133, but I just obtained 2.5 on a recent Pentium 133. Sun machines are much less available, but they always have the same architecture, given the model number. My hope is that availability will not be an issue, as long as we are on the Internet. However the problem exists. Opinions? Also, how about keeping the results obtained with older versions of Octave (at least for runs on the reference machine) so that we can easily see if Octave is getting faster or slower as it gets older.
