ADGPS performance on various systems

<< < (2/2)

Josh:
In the win systems, try setting the quanta to background rather than programs. This makes the timeslices equal for background and foreground apps but it makes them all longer. Normally one has the programs set to receive lowest latency, wich can starve background processes. Test in both modes and see if there's a diff in performance.

ChrisSmolinski:
I ran a test with the frequency step range set to -5 to +5, also in 5 Hz steps, and it ran at about 7x real time, vs 4x when set to -15 to +15. I was doing some tests to see how that affected pulling out weak decodes, and while similar, it is very slightly less.

But more interesting (and I have seen this before) you also get slightly different results running the same exact file more than once, even with the same settings. I think skeezix may have noticed this before as well. I'm not sure what the cause is. It is both puzzling and disconcerting.

skeezix:
Yes, I definitely noticed that running the same recording through with no changes at all results in slightly different numbers of decodes.

Apparently I need to find better quality Heisenberg compensators
