I have been lurking on this list quick some time now; but I have never seen a
discussion regarding how to calculate the optimum amount of RAM required for
XFS based filesystems.
There was a thread a very long time ago (cannot find it now) where it was
stated that leaps of RAM was required but didn't specify the quantity of
heaps ;-) For memory it also discussed the caching of filesystem data for
performance. But I don't think the interaction between amount of RAM and XFS
was discussed fully.
Does anyone have experience on this subject?
Say - how much RAM is required for a 80G or 120G XFS file system?
Does having many different sized XFS partitions change anything?
For example I have 1x 40G, 1x80G, 1x120G XFS partitions on the same
fileserver with 384M RAM. Is this enough?
