Re: Building a new workstation - dual or quad-core CPU for FreeBSD 7?

Yes, 4BSD is still the default, although you definitely want to use ULE for performance reasons (NB: only on 7, dont use ULE on 6). I don't know whether the release engineers plan to change that default, but I will check. could you point to some URL/explain what's the actual difference.

Windows XP, which will be primarily used for gaming, and FreeBSD 7.0 for everything else. I wanted to ask if the new ULE scheduler will benefit from having four cores on the CPU, meaning that if I have many concurrent tasks, is it able to efficiently spread the load over all available cores?

In general, if you are running a multi-process or multi-threaded workload, FreeBSD 7 will be able to make good use of 8 CPU cores. Over the past 2 years we have done extensive benchmarking and optimizations that have resulted in *huge* performance improvements on many common workloads on
