I performed the same measurement on ext4 with the default options.
Here is its result:

    filesystem        time(sec)  call extX_mark_inode_dirty(times)
    ---
    ext3              220.5      50,338,104
    ext3 (patched)    196.3      25,169,658
    ext4 (*1)         190.3      28,465,799
    ext4 (*2)         201.5      27,963,473
    ext4 (default)    223.3      14,026,118

    *1 disable ext4-specific options (delalloc, extent, and so on)
    *2 disable only delalloc option
