I switched back to Newsbin from Newsleecher after a loooong time and like Newsbin just fine.
There is just one major problem which drives me insane:
When I update a group which has let's say 600.000 new headers it takes over an hour until the group is updated. I went through several betas with no change.
In Newsleecher this would take about a minute and I would be done. What could be the cause?
