[Lustre-discuss] Small files performance

[Arne Wiebalck]

Dear list,

We're currently experimenting with Lustre and small files (<=1MB)
and some questions came to mind:

- will writing files that are smaller than the stripe_size and that
   are written to a fully striped directory create objects on more
   than 1 OST?

- what would be the main options to tune in order get the best out
   of Lustre for small files? (If the answer to the 1st question is
   'yes', then 'avoid striping' would be a first candidate, I guess ;)


TIA,
  Arne
