Sorry for my delay, I spent a longer time ill in bed and didn't had the time to
go on in testing the system:

Hi roy, Hi Dan,
many thanks for Your responses.
I am using napp-it to control the OpenSolaris-Systems
The napp-it-interface shows a dedup factor of 1.18x on System 1 and 1.16x on
System 2.

Dedup is on always (not only at the start), also compression is activated:
System 1 = compression on

But is the L2ARC also important while writing to the device? Because
the storeges are used most of the time only for writing data on it,

Dedup is known to require a LOT of memory and/or L2ARC, and 24GB isn't really
much with 34TBs of data.
The fact that your second system lacks the l2arc cache device is absolutely
your prime suspect.

3G per TB would be a better ballpark estimate.
