Recent -stable (9 and 10) already has the fixes. Tricks: we support dirindex now so you can set it in e2tunefs. If you are not satisfied with performance, you can also try running it async as linux does. JIC you feel adventurous and want to give a try rebuilding your own kernel for fun. :). This said, I don't recommend ext2fs for anything serious. I have some interest in resurrecting the MacOS X UFS1 support and perhaps get it to a point where it supports softupdates, but I don't know yet sufficient about kexts. Pedro.
