Hi Igor, Quoting Igor Stasenko <siguctua@gmail.com>:
i just wonder, what takes so much CPU time, even if it completely idle...
4831- NBCog 4.8 51519- NBCog 3.5
if i kill a UI process, the load goes down to 2.5-3 % ... still too much.
Well, there are both image and VM issues here. I'll assume you're running Pharo on a Mac. Running Cuis on a Mac, when idle, uses 2.6 - 2.7%. So, the UI process can be optimized to the point where it takes almost zero CPU. But there are VM platform code issues too. Doing the same on a Windows 7 Atom netbook, Cuis uses 0% (zero!) CPU.
i would like to know how we can minimize this. The reason why i concerned is straightly pragmatic: extending battery life..
i found that if i run completely on battery.. it depleting quite fast with VM running (and i don't do anything just coding, i.e not running benchmarks, but more thinking and typing).
