Hi enealDC,
good hint on the memory, but at the moment of the 4 GB less then 1 GB is used...so I dont think about a bottleneck in this area...?

On jumbos I get a decrease of throughput of about 15%...and we have already really little throughput. On the replication interface (which is dedicated!) I only have a max of 100Mbit in peaks...
So my performance of the iSCSI disks using the storage is between 4000 and 7000 K / sec.
