Can you try with pax? (pax -rw ...)  That doesn't involve pushing the 
stuff thru a pipe like with tar.  The cpio version is similar but it 
probably can be sped up a bit if you run the find once before, or feed 
find into a file and redirect input to cpio from that file (so that it 
doesn't have to seek all the time.)
