I have switched today all my devices to the BOINC version 6.10.18 for 64 bit Windows. Let's see if this improves the number of results per day.

Hate to be disappointed too. But it happens. That's life.
I should have thought of that.

I will still see if there is some difference. A more effective traffic warden may in the end have better results as a whole.

To simplify,
Consider Boinc as a tool for downloading and uploading tasks and managing when tasks run - a sort of task manager.
When you sign up to WCG you download a WCG Master file.
This is the actual program that runs the tasks, not Boinc.
The tasks are the same no matter whether you have a 32bit or a 64bit operating system - they are all x86.

So you were already running the tasks on a 64bit operating system, and the tasks would therefore already have been benefiting from the 64bit operating systems ability to handle itself and x86 tasks to some degree.

Perhaps the 64bit Boinc system is slightly better at handling tasks on a 64bit operating system, or more stable. I expect there is some small difference; otherwise the authors would not have bothered to write it!

It would benefit those of us that have 64bit Operating Systems if tasks were written specifically for our benefit as well as seperate x86 systems. Another 10% or 20% boost is something I am sure the scientists would like to see as much as us. Perhaps some tasks will eventually be written specifically for 64bit systems?
