Re: Best Logfile size for XFS
Hi,
Well, I don't think you should worry about performance in this case.
There's only metadata going into the logfile and considering the number
of files you're going to have on that partition (less then 20) you'll
hardly have a write into the log. Please correct me if I'm wrong.
On the other hand you could play with the realtime option, but I
don't know if it's been implemented yet or not.
