Understanding performance with Google Benchmark @ Italian C++ MeetupDecember 13, 2018
During the last meetup of the Italian C++ Community in
Modena, Italy I had the chance to give a talk about profiling C++ code. The whole game
boils down to understanding what's going on when you have to cope with very smart
optimizing compilers, NUMA architectures and speculative, superscalar CPUs: in this quest
for knowledge we are lucky enough to have some extremely useful tools like the holy
perf and micro benchmarks, using the excellent
Google Benchmark for instance.
It has been a lot of fun!
Thanks to all the attendees and to Marco Arena for the chance to prattle on about some fun stuff I enjoy.
