What if your 32bit system is just a NAS -- ZFS and NFS, nothing else? I think it would still be ideal to allow tweaking of things at runtime to make 32-bit systems more ideal.

Yup, your probably running up against the limitations of 32-bit kernel addressability. We are currently very conservative in this environment, and so tend to end up with a small cache as a result. It may be possible to tweak things to get larger cache sizes, but you run the risk of starving out other processes trying to get memory. -Mark Robert Milkowski wrote: > Hello zfs-discuss, > > Simple test 'ptime find /zfs/filesystem >/dev/null' with 2GB RAM. > After second, third, etc. time still it reads a lot from disks while > find is running (atime is off). > > on x64 (Opteron) it doesn't. > > I guess it's due to 512MB heap limit in kernel for its cache. > ::memstat shows 469MB for kernel and 1524MB on freelist. > > > Is there anything could be done?
