It would be more work for the first architecture, and I am up to the task. Additionally, it does prove my point -- because it would show that the OSes (except for performance and specific features) are essentially interchangable. >But I don't have any real numbers to back that up either. Maybe someone >could do a benchmark of some sort to compare NetBSD and FreeBSD (in their >most recent versions?). That would be interesting. It only makes sense on the same code base (say NetBSD 0.9 Net/2 vs FreeBSD V1.1.5 Net/2), or the first 4.4Lite Netbsd vs the first 4.4Lite FreeBSD (which should be out within a month or so of each other.) Also, it only makes sense comparing released code. I know that comparing NetBSD 0.9 vs. FreeBSD 1.1.5 sounds unfair -- but those are the last Net/2 releases. Additionally, it would be best to TRY to compare two releases that are released at approx the same time. It is unlikely that NetBSD will have two releases before FreeBSD gets its V2.0 out -- but it is possible. The results of comparing FreeBSD V1.1.5 vs NetBSD (1.0) would be screwy. You would find that the file performance of the 4.4Lite based code would be faster, but the VM performance for process startup and I/O to VM space would be slower (under some circumstances.)
