I'm using it under light-to medium load for a few months now, both on d= esktops=20 and test server. In v2.6.39 it seems rock solid -- but that's just hear= -say=20 evidence. On caveat applies: under certain workload, current implementation suffe= r from=20 high file fragmentation. That workload for me is Bitcoin, which modifie= s a lot=20 of data in Berkley DB with pagesize 4kB. Also, BDB in Bitcoin issues fs= ync()=20 or similar after every disk write, which creates lots of checkpoints, e= ating=20 up diskspace with metadata. But that's an extreme case; for general use NILFS2 is a-OK. Regards, --=20 dexen deVries > (...) I never use more than 800Mb of RAM.
