I recently managed to keep BOINC from prefetching GFN tasks which caused each task to have a 2 minutes longer send/receive duration. I didn't see any change in the "first ratio", though.
The reason being, nearly all tasks where I'm second the other host got the task 10-15 minutes earlier than me. With these short tasks that means, they are first. Of course, the same is true other way around, I often get 1st against 2080s just because I got the task 10 minutes before them.
Accordingly, 1st ratio is around 50%, since it's randomly decided who gets the task first. This might even be a good thing, but I'm not so sure. :) Is there a way to prevent this from happening or are the GFN tasks so rarely fetched that it cannot be helped? It's GFN17-mega.
