Indeed, measuring performance is tricky and chasing slow downs can be challenging especially  those at the level of ~0.2%-0.1% or less. 
Personally, every time when I need to use perf on Clang I follow those short guidelines to reduce noise and get relevant numbers: https://llvm.org/docs/Benchmarking.html#linux
It contains some extra information about controlling mentioned ASLR (via *randomize_va_space), SMT, cpu isolation and more.
