Thread-topic: XFS memory recomendation?
Thanks for the answer Dave and Michael.

As you might realize, I have no knowledge if the internal works of
XFS :-P 

My problem is that the file system sometimes seems to be a bit laggy
when listing directories and so on. I really don't know how to deal with
it. I guess more memory always will help but where should I put the

Can it be a solution (ugly) to warm up the cache by making a complete
"find" on the file system sending output to /dev/null? but then again it
would probably be a stupid way to use precious memory for something that
isn't used that often.
