A quick comparion for Delays:
delay := Delay forMilliseconds: 1.
bag := Bag new.
1000 timesRepeat:[bag add: [delay wait] timeToRun].
bag sortedCounts
on my 4-core box it yields:
- with AdvancedProcessorScheduler install
a SortedCollection(951->2 49->1)
- with Processor fallbackToOldScheduler
a SortedCollection(953->2 47->1)
- with old VM
a SortedCollection(952->2 47->1 1->3)
not much overhead huh? :)
But Delay's code now can be refactored, which will simplify it
seriously, because it could run in interrupt process and take no care
for concurrency issues.
