When I'm in the Transfers tab my downloads go slow. When I go to the Bandwidth tab (or another tab) my downloads immediately go fast. Why? Tixati 2.57 on Win10 64bit.

Researching this, it seems to be caused when I have loaded Tixati with too many (thousands) transfers. It does not seem to be related to active downloads, but only to total transfers (whether completed or not, and whether started or stopped).
