Hi guys - I'm really looking forward to 5.3 for the potential of ext4. I am moving/copying image files lately 8G file and it is slow. I am hoping that ext4 really speeds that up.
I don't think it will speed things up much. 8GB files are mostly hardware throughput and ext3/4 will actually be slower because the journalling etc are to make it more robust but at a speed cost. You would probably see better speed by going to ext2.
I make it a habit of eating my own words if I screw up. If the results seen on Ubuntu by one test hold up, it might have a large increase in large writes (but nothing in large reads).

Has anything fixed fsync so it works as intended on a single file without waiting for the whole filesystem metatdata to be written?
