Just interested, as I do get enough to keep it running 99% of the time, but I remember when there was a limit of 80 at once (per machine or card I forget which). Now I seem to get 600 at a time, but it waits until they're all done before I can get another load. Although if I pause the GPU when I'm playing a game, then I seem to get a topup. How is the download limit calculated?

It seems to be set that you have to wait 10 minutes of no communication with the project before you get new wu's. Everytime you report a completed wu the timer starts again.

Ok, that tallies up with what I'm seeing here. Can I change a setting at my end to make it only report tasks every 15 minutes?

I assume the admins have done this to reduce server load. I find it absurd that my Boinc client is reporting 3 tasks as completed every 2 minutes after having downloaded a block of 600. This seems to be adding unnecessary server load. Why can't it report only once every half hour?

And can't the server set a limit on contact frequency? For example currently in my Boinc manager in the projects tab, I see Universe saying "communication deferred" with a countdown of 25 minutes. This is because they're doing a server upgrade and don't want pestering. Presumably with each contact the client makes, the server, after performing the request, can say "don't speak to me again for x minutes"?
