using XFS for sequencial read from multiple large files

[Roy Sigurd Karlsbakk <roy@xxxxxxxxxxxxx>]

hi

I want to sustain pretty high speed while reading files 1-5 GB in size. I
also want to add / remove / replace these files every now and then.

- How should I create the filesystem? Should I use the defaults?
- How can I avoid fragmentation? The filesystem will probably be close-to
  full most of the time. I can probably live with quite some
  fragmentation, as long as the fragments are of a fixed size (say - 4MB).
  That way, I can increase the /proc/sys/vm/(min|max)-readahead to that
  value, reducing the effect of fragmentation. I beleive this might be
  true...
- When trying out ReiserFS, I got a tip to mount the fs with 'notail'. Is
  there something like this in XFS?

Thanks a lot
