As requested earlier by Vincent, I threw together a little benchmark 
program (attached) comparing the speed of boost.signals with signals2.  It 
produces the following output on a P4 running Linux:

boost::signals2::signal, 1 connections, invoking 1000000 times: 0.20 s

boost::signal, 1 connections, invoking 1000000 times: 0.26 s

boost::signals2::signal, 10 connections, invoking 1000000 times: 0.77 s

boost::signal, 10 connections, invoking 1000000 times: 0.91 s

boost::signal, 1 connections, tracking enabled, invoking 1000000 times: 
0.28 s

boost::signals2::signal, 1 connections, tracking enabled, invoking 1000000 
times: 0.72 s

boost::signal, 10 connections, tracking enabled, invoking 1000000 times: 
0.78 s

boost::signals2::signal, 10 connections, tracking enabled, invoking 1000000 
times: 4.92 s

boost::signals2::signal, connecting 1000000 connections then disconnecting: 
0.87 s

boost::signal, connecting 1000000 connections then disconnecting: 2.13 s
