Thanks for the numbers!
Excellent stuff. would like to add the note that in an "ideal" deployment of the ActiveObject pattern, it brings zero overhead. Thats a wee bit sensational to make the point. but the overheads incurred with mechansims such as inter-thread messaging were there anyway. so yes copying, queueing, dequeueing and signaling a thread all consume cycles. but the application would have had to do something similar. ActiveObject is just a formalization and acknowledgement of it.
Hmm, thank goodness that emacs/gnus has a "Capitalize" key command for messages like this one. Sadly, it didn't fix everything ;-) Are ActiveObjects like all objects were in Simula: each running in its own thread, with fully asynchronous inter-object communications? -- Dave Abrahams Boost Consulting www.boost-consulting.com
