The only way to know for sure is to give it a try or
OF course you'll buy that, because my suggested workaround worked ;) > profile the run, but I think it is very likely to be allocator related. First I decided I need a profile run, but once I realised how small created files are, and looked on the on-disk block distribution chart. Then I remembered on what basis we choose 1st block of a file to be allocated, and I realised I do not need profile run ;) In fact I am interested in similar task performance of ext3, since I've yet to try it.
