I have been running -CURRENT since just before 5.0 was released and have seen the introduction of the ULE scheduler and the associated mails on this list about it. I know it used to be classed as very experimental and you should use 4BSD if you want stability etc. I was wondering if that is still the case these days? The other question which I am not too sure about is what are the advantages of ULE over 4BSD or vice versa? I know a lot of people will now probably say "stick with 4BSD if you don't know" or something and I will if ULE is still not recommended for general use. But I am just curious to learn a bit more about it. Regards, Matt. -- email: matt@xtaz.co.uk - web: http://xtaz.co.uk/ Hardware, n.: The parts of a computer system that can be kicked.
