Benchmarking 7.0 performance

[Tim Selander]

I don't know about benchmark on routines, but I have created a 
measly 10MB file -- customer database -- and saving changes to 
the file takes a full 10 seconds or more. That seems pretty slow 
to me. Duplicating the file in Finder takes a fraction of a 
second. Saving an edited 10MB .wav audio file takes a fraction of 
a second.

Why is saving the stack so slow? This is going to be a real pain 
for my data entry lady who is used to HC saving everything 
automatically and invisibly....
