I wasnt clear in my description, I m referring to ext4 on Linux. In
fact on a system with low RAM even the dd command makes the system
horribly unresponsive.
IMHO not having fairshare or timeslicing between different processes
issuing reads is frankly unacceptable given a lame user can bring
the system to a halt with 3 large file copies. Are there ZFS
settings or Project Resource Control settings one can use to limit
abuse from individual processes?
I am confused. Are you talking about ZFS under OpenSolaris, or are
you talking about ZFS under Linux via Fuse?
Do you have compression or deduplication enabled on the zfs
filesystem?
What sort of system are you using?
