Actually we have some compile bench numbers (coming to this list soon) that also surprised us. The stages of compile bench that I believe are dominated by directory operations are also showing improvements without the journal. > Maybe trying dbench (I know it's kind of stupid ;) or > postmark will show the differences better.
