Hi again,

Should I use gjournal on FreeBSD 7? Or just soft updates?

Here is my opinion: I suspect that gjournal would be much slower than
soft updates. Also gjournal is relatively new code, not very well
tested. But gjournal is better when the system crashes. Although I have
heard that sometimes gjournal will crash the system itself. There are
more pros for soft updates I would pefer that. But please let me
know if I'm wrong.

Thanks,

   Laszlo
