We were told that, as of Android 1.6, background processes were put in a Linux process scheduling class that limited how much CPU they would use. A few weeks ago, I ran a benchmark test that seemed to validate this claim.
I have run more tests, and I am no longer confident in my earlier conclusion. I can get a background process to significantly impact the foreground process, more than would seem to be possible if the background process was, indeed, CPU-limited. Details, including sample code, can be found in the issue I opened that was promptly closed: http://code.google.com/p/android/issues/detail?id=7844 Clearly, the failed issue was my fault, for not running around screaming about bugs in Android and not jumping to conclusions. Anyway, if anyone else has any ideas on how we can prove whether background processes are CPU-limited -- and if so, how come that's not helping much -- please respond to this thread or shoot me an email off-list if you prefer. And, I apologize to anyone who took my prior advice regarding this CPU utilization, as it looks like I screwed up big-time on that analysis. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
