Um that's not what I've seen and reported. I've seen operations as 
simple as checking to see if a tag exists take as long as 30 or 40 min 
on a large binary ,v file. If memory servers, it appeared that it was 
loading the entire file into memory and the server ran out of RAM and 
started thrashing on the disk.
