While they in fact took about 30 hours to complete, I only got around
to packaging them up now. Unfortuantely the tests were incomplete as
I needed the machine back for another use but the results that did
complete are at http://www.csn.ul.ie/~mel/postings/hnaz-20110729/

Look for the comparison.html files such as this one

http://www.csn.ul.ie/~mel/postings/hnaz-20110729/global-dhp-512M__writeback-reclaimdirty-ext3/hydra/comparison.html

I'm afraid I haven't looked through them in detail.
