QUESTION
I tried to call the isSpaceAscii
from the standard library but got worse performance than with my own proc.
Code to reproduce:
...ANSWER
Answered 2021-Feb-10 at 19:58Benchmarking is hard, because you're not always measuring what you think you're measuring.
The incredibly stark differences you're seeing are because the isSpace
loop doesn't do anything, and is in the same compilation unit as the isSpace
function, so the compiler can optimize it away
as you can see on godbolt
if you instead compile with -d:release -d:lto
the compiler will perform link-time optimization, and will optimize away both versions.
QUESTION
I use this function to init logging with boost and it works well
...ANSWER
Answered 2020-Jul-29 at 16:26Boost offers a monotonic clock boost::log::detail::get_timestamp()
It's a bit misleading to say it "offers" that. It's expressly in a detail namespace so you cannot rely on it.
Is it monotonic?It turns out that on POSIX the implementation is switched anyways:
