what is the advantage or disadvantage of limited the ZFS cache??? Additionally does it depend on system size; ie. how large the - and how many hard disks there are?? So say for a system with 2GB memory if the app + kernel + background procs takes up 1.5GB then if one limits the ZFS cache to 512MB what significance does this have?? Regards and apologies for the intrusion!! Kaya
