There have been many similar posts and explanatory replies about this sort of thing. There may even be a FAQ on it (but I haven't checked). It is an artifact of how memory allocation works and improved efficiency of memory algoritms. So, do a little archive and FAQ searching. There may also be articles in online publications such as Onlamp or others. ////jerry > > Thanks in advance for any help. > > Roselyn > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
