## +23 ## Optimizing Away Virtual Functions May Be Pointless ## SHACHAR SHEMESH Slide #2 - who am I?  ## DO NOT ENTER reviewer's notes: There are interesting technical details and surprising conclusions that virtual functions can be actually faster. Since CPU architectures are mentioned, I'd expect to see deep assembly vtable lookup. Does it even matter? ### WEKA DriveU.auto ## Conclusions - The notion that “virtual functions are slower” is flat out wrong. ○ Which is not to say they are faster o Some of the suggested alternatives
