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. -- Mel Gorman SUSE Labs
