Its a case of trial and error as to the settings..... the suggested setting for your pc is a good starting point..... leave your incoming unticked and work upwards from the 6000 sugested for outgoing and see what works best for yourself ...although 6000 does seem a little low...personaly i run at around 40000 this still allows me to download at reasonable speeds as well as use other apps depending on what project i am working on at the time....if i am away for any amount of time i tend to untick the outgoing thus allowing ppl who are downloading files from me to benefit from faster speeds if there pc allows them to.
