Setting timer interval to 100ms causes high CPU usage

Open gyk opened this issue 8 years ago • 2 comments

When calling timer.interval(Duration::from_millis(100)), the program takes up almost 100% of the CPU cycles, but after changing the interval from 100 to 101, the CPU usage dramatically drops to nealy 0%. Tested on macOS 10.12 with Rust 1.17.

Here is my code, you can reproduce it with cargo run --release 1000 100 and cargo run --release 1000 101.
