So, If I understand you correctly, it is your position that the load is
slow because of "I/O limited wrt shell". I do not believe that this
explains the slowness of the load. As I mentioned before, I removed the
.attr files. Since then I do not get _any_ warning messages during the
load but the load is still slow. Therefore, I can only assume that it
is not I/O bound. I also mentioned in another message that the database
is made up of several files and "I can load each file individually with
perfly in about 3 to 4 seconds."

I am still left with the belief that "fixing" this database is the correct
course of action. I assume I can fix the database with version 14.0.?.?

Rest assured that I will replace the .attr files and start from there.
