Doug, Following up my previous message, I have run the tests with Boost 1.32.0 and can see what you mean about a drastic improvement. The full set of figures are: VC8.0 GOF Observer: 109 VC8.0 Signals 1.33.0: 6203 VC7.1 GOF Observer: 78 VC7.1 Signals 1.32.0: 112109 It's interesting that the Observer pattern is actually slower with VC 8. - Keith MacDonald "Doug Gregor" <dgregor@cs.indiana.edu> wrote in message news:9d494fe2c9d82d8a37c8c9a18f1b553e@cs.indiana.edu...
The performance of Signals has been drastically improved in 1.33.0 thanks to a patch from Robert Zeh. It may still not be as quick as a specific implementation of the Observer pattern, but it's much more reasonable now.
