Benchmarking is complex ;) 1. you need to make sure both Qt and your benchmark are built with optimizations enabled (-O2) 2. you need to actually use those 3 variables otherwise the compiler might optimize out their use. This could be testing their value (NOT with Q_ASSERT if you're in release mode!) and aborting if they don't have the expected value. They will, of course, but the compiler won't know that. Your current results indicate "54 times slower" ! But indeed on very small numbers...
