Thanks for the info.

Norbert, I didn't knew about that UI thread handler in Seaside. I'll check that out.

It would definitively by better if we could get CPU usage when idle very close to 0%.

But IMO the current situation is not really a problem. Actual load problems will still be caused by real load, not by idle instances. Anyway, that is what I see on production machines with multiple Pharo instances next to many other processes.

BTW, load & cpu usage numbers can be very hard to interpret.
