[NILFS users] cleaner cpu usage

[David Arendt]

Hi,

I am currently testing nilfs on a 1TB partition with 600GB of data. I
noticed that I sometimes have through several hours 20% cpu usage by the
cleaner. During the 20% usage, I have 50% iowait, leading to an overall
slower system. Is this behaviour normal or is there something I can do
on my part. If this is normal, I think it should be possible that I
mount without cleaner and start the cleaner only if I am short on space.
Is there any argument against doing this ?

Concerning stablility, I didn't have a single crash until now.

Thanks in advance
Bye,
David
