Good morning,

I'm running IOzone on a NILFS2 partition and it's running alot
slower that I had expected. I'm pretty sure it's because of the
checkpoints. I can change the protection_period to something
very small (or zero). Would that improve the performance?

In addition, is there a way to turn off checkpointing?

Thanks!

Jeff
