[Boost-users] Re: [Signals] Observation about performance

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.

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.

It's nice to see that my patches had an impact! I'm working on improvements (suggested by Doug Gregor) that replace some boost::any usages with template classes. This should make the library faster by removing some of the memory management it does. Is your application openly available? I'm always looking for more benchmarks. Robert Zeh
