ahhh very obervant Mickey. That is correct.. the ratio for uploads on max ix 4 simultaneous. You would not want to be bogged down with more concurrent ones then that ( so xolox feels). The speed however should not be effected once set to Max.

The speed you choose for upload directly correlates with how many simul. downloads and uploads you can have - as well as node connections. It's a good ratio to make things balanced to ensure fairness and reduce leeches.
