Thanks for your replies.
Achenle, here are the outputs of "prstat -a", "vmstat 2 20" & "iostat -sndxz 2 20".
And yep I think the 'solution' to this performance issues before was the "throw as much CPU against it and hope if that resolves it"-approach.. . Which clearly didn't have the hoped for effect.
