    Hi,&#10;I do not agree with most authors regarding UP vs. MP performance.&#10;There is a benchmark suite (not first microbenchmark suite) that shows resource allocation under NetBSD is faster.&#10;That's all there is to it. Not more or less...&#10;By performance we mean an array of properties for me it starts with throughput.&#10;To measure performace we would have run things like TPC-C and other workload simulation tests.&#10;Back in a day Linux was being tuned to show better LMBench numbers. Everyone knows what happened with that.&#10;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.&#10;Let's take things for what they are.A microbenchmark shows that some NetBSD allocators scale better.&#10;A microbenchmark cannot give any results that could be used to realistically assess an overall performance.&#10;igor.
