Benchmarking
This crate can be used to execute something and measure the execution time. It does not output anything to screens and filesystems.
Examples
extern crate benchmarking;
const VEC_LENGTH: usize = 100;
benchmarking::warm_up();
let bench_result = benchmarking::measure_function(measurer {
let mut vec: Vec<usize> = Vec::with_capacity(VEC_LENGTH);
unsafe {
vec.set_len(VEC_LENGTH);
}
for i in 0..VEC_LENGTH {
measurer.measure( {
vec[i]
});
}
vec
}).unwrap();
println!("Reading a number from a vec takes {:?}!", bench_result.elapsed());
extern crate benchmarking;
const VEC_LENGTH: usize = 100;
benchmarking::warm_up();
let bench_result = benchmarking::measure_function(measurer {
let mut vec: Vec<usize> = Vec::with_capacity(VEC_LENGTH);
measurer.measure( {
for i in 0..VEC_LENGTH {
vec.push(i);
}
});
vec
}).unwrap();
println!("Filling 0 to 99 into a vec takes {:?}!", bench_result.elapsed());
extern crate benchmarking;
const VEC_LENGTH: usize = 100;
benchmarking::warm_up();
let bench_result = benchmarking::measure_function(measurer {
let mut vec: Vec<usize> = Vec::with_capacity(VEC_LENGTH);
for loop_seq in 0..VEC_LENGTH {
measurer.measure( {
vec.push(loop_seq);
});
}
vec
}).unwrap();
println!("Pushing a number into a vec takes {:?}!", bench_result.elapsed());
extern crate benchmarking;

benchmarking::warm_up();
let bench_result = benchmarking::measure_function_n(2, measurers {
let mut vec: Vec<usize> = Vec::with_capacity(VEC_LENGTH);
for i in 0..VEC_LENGTH {
measurers[1].measure( {
vec.push(i);

}
for i in 0..VEC_LENGTH {
measurers[0].measure( {

}
vec

println!("Pushing a number into a vec takes {:?}!", bench_result[1].elapsed());
 The
warm_up
andwarm_up_with_duration
functions of thebenchmarking
crate runs on one thread. To warm up all CPUs, you can use thewarm_up_multi_thread
andwarm_up_multi_thread_with_duration
functions instead.  The
measure_function
andmeasure_function_with_times
functions of thebenchmarking
crate can execute a closure for N times. To execute it repeatly for a while instead, you can use thebench_function
andbench_function_with_duration
functions.  To execute a closure with multiple threads to measure the throughput, you can use the
multi_thread_bench_function
andmulti_thread_bench_function_with_duration
functions of thebenchmarking
crate.
