Hi Igor,

Quoting Igor Stasenko <[email protected]>:


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).

Igor Stasenko.
