ok ;) Did that (camcontrol), with the following result:

Operations performed:  6006 Read, 3994 Write, 12800 Other = 22800 Total
Read 93.844Mb  Written 62.406Mb  Total transferred 156.25Mb  (1.4742Mb/sec)
   94.35 Requests/sec executed

which is already a lot better but still below the IO of the local disk.
Should I try more right now or should I wait for more progress in that?

Does it make sense to switch to -CURRENT for that?
