If you are well familiar with some particular flavour of Linux, then you will likely have an easier time making it perform well than jumping to some other OS where files are in different places and the knobs you have to tune are different from the ones you already know about. If you are well familiar with some particular flavour of BSD, then you will likely have an easier time making it perform well than jumping to some other OS where files are in different places and the knobs you have to tune are different from the ones you already know about. The learning curve is entirely likely to be expensive enough as to outweigh any kinds of short term benefits you might find. -- let name="cbbrowne" and tld="cbbrowne.com" in String.concat "@" [name;tld];; http://cbbrowne.com/info/rdbms.html I am not a Church numeral!
