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
