Just keep the following in mind: 1. Although NetBSD did perform better on many of the benchmarks (kudos to them), but the difference is usually not dramatic. 2. The benchmarks are strictly uniprocessor benchmarks. 3. The author does admit at the end of the article that NetBSD still uses a big, giant lock around the kernel and the benchmarks might be very different on a multiprocessor system. 4. The benchmarks are only NetBSD versus FreeBSD, so it's hard to judge where the performance of each system fits in the grand scheme of things. It could be that both systems are performing very well. The benchmarks need to include at least one non-BSD system (usually Linux) in order to get some perspective. 5. It would have been nice if FreeBSD 4.10 and NetBSD 1.6.2 were also include, so we could see the relative progress (or lack) of each system. But it's worth reading. Data is always a good thing. Just don't get hung up on them. Hopefully, it will inspire more comprehensive tests. Richard Coleman rcoleman@criticalmagic.com
