Yup, on the whole, in order to increase performance, you don't want more and more nodes to be contacted. Remember that every txn has to have a minimum of F+1 replicas vote on each txn, so if F is really large, although they vote in parallel, you have greater chance of network delay and greater load on all machines. So GoshawkDB allows you to increase cluster size without increasing F, so getting you greater performance.
