Ken, You have to remember the age of the program. When these messages about speed came out we were using 486's and maybe 386's. The messages are some of those wish list items that never got taken care of.
Every time you do a backup you get the message that it will take time to do the job. You have to click OK then it starts. One more way to ask what were they thinking about. On a 450 things are much faster than a 166 or 133 but I wonder what a 1.5 or 2g is like.
Course I remember also when we ran optimise over night too with a Roots program.
