Hmm, wir kommen zwar immer weiter vom EMule Thema weg, aber hier passt es am besten rein:
Ich hab mich mal wegen diesem Bandbeitenklau umgeschaut und auch Lösungen gefunden.

SpeedUp Your Connection By 20% (Cable Users Only)

1.Log on as "Administrator".
2. Run - gpedit.msc
3. Expand the "Local Computer Policy" branch.
4. Then expand the "Administrative Templates" branch.
5. Expand the "Network" branch.
6. Highlight the "QoS Packet Scheduler" in left pane.
7. In the right window pane double-click the "Limit Reservable Bandwidth" setting.
8. On the settings tab check the "Enabled" item.
9. Change "Bandwidth limit %" to read 0.
10. Then go to your Network connections Start=>Control Panel>Network & Internet connections>Network Connections and right-click on your connection. Then under the General or the Networking tab, (where it lists your protocols) make sure QoS packet scheduler is enabled.

It may take effect immediately on some systems. To be sure, just re-boot.

Hope everyone finds these useful.
Aber dies funktioniert nur unter XP Prof. Ich habe aber die Home Edition.
Was soll ich tun? Hab dazu nichts gefunden.
