It has been a long time since I worked with a ZFS filesystem, but I don't think it is unusual for ZFS to consume memory that is otherwise unused as a cache for ZFS disk data.

Reading 33Mb/s and writing 7.5Mb/s may seem high, but with 0 wait time on the device, it doesn't appear to be a problem.

Are you seeing a high swap rate (or any indication that running processes are running poorly due to a lack of available memory)?

NAME
zdb - ZFS debugger SYNOPSIS
zdb pool DESCRIPTION
The zdb command is used by support engineers to diagnose failures and gather statistics. Since the ZFS file system is always consistent on disk and is self-repairing, zdb should only be run under the direction by a support engineer. If no arguments are specified, zdb, performs basic consistency checks on the pool and associated datasets, and report any problems detected. Any options supported by this command are internal to Sun and subject to change at any time. EXIT STATUS
The following exit values are returned: 0 The pool is consistent. 1 An error was detected. 2 Invalid command line options were specified. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWzfsu | +-----------------------------+-----------------------------+ |Interface Stability |Unstable | +-----------------------------+-----------------------------+ SEE ALSO
