Benchmark: NetBSD 2.0 beats FreeBSD 5.3

Hi, I do not agree with most authors regarding UP vs. MP performance. There is a benchmark suite (not first microbenchmark suite) that shows resource allocation under NetBSD is faster. That's all there is to it. Not more or less... By performance we mean an array of properties for me it starts with throughput. To measure performace we would have run things like TPC-C and other workload simulation tests. Back in a day Linux was being tuned to show better LMBench numbers. Everyone knows what happened with that. Assuming that root of a problem is number of CPUs is not warranted, unless someone actually did comparison and concluded that NetBSD resource allocation does not scale across multiple processors. Let's take things for what they are.A microbenchmark shows that some NetBSD allocators scale better. A microbenchmark cannot give any results that could be used to realistically assess an overall performance. igor.
