I don't see any benchmark related to file deletion on that article, and 
in fact deletion of large files is a fairly atypical usage pattern. 
Mythbuntu has defaulted to EXT4 for several years now, and I've not 
heard any problems of people having to enable the 'slow deletes' option 
in MythTV intended for EXT2/3.
