A benchmark of three C++ open source callback/signal/slot ... The callback list (signal) performance of cpgf callback, for a single slot (note it's 5 slots in a signal in the benchmark) is 50% slower than one single slot call without callback list. That means if there are 10K slot invoking, only 0.2ms is spent on the invoking itself. GitHub - zhanggyb/sigcxx: A simple C++11 signal/slot (event ... The concept is that objects (typically GUI widgets) can send signals containing event information which can be received by other objects using special functions known as slots.
