On: Qt signal is ten times slower than a virtual funct...

This has been documented for eons.

https://doc.qt.io/qt-5/signalsandslots.html

"Compared to callbacks, signals and slots are slightly slower because of the increased flexibility they provide, although the difference for real applications is insignificant. In general, emitting a signal that is connected to some slots, is approximately ten times slower than calling the receivers directly, with non-virtual function calls."

"A month in the laboratory can often save an hour in the library."

My criticisms of Big Tech fall down the cracks, but hey, failure to read the fucking manual makes it to the HN front page.

The documentation literally says ten times slower.
