This document discusses benchmarks for analyzing software and hardware performance. It defines benchmarks as tests that measure performance and enable comparisons between products. The document outlines different benchmark modes for software vs hardware, potential issues with benchmarks like cheating and virtualization, and gives examples of when benchmarks are important, such as for complex routines or generic components requiring full efficiency. It also lists organizations like SPEC and EEMBC that standardize benchmarks and provides a code example for using the BenchmarkDotNet library to run benchmarks in .NET.

3. BenchMarking (business) vs BenchMark (software)
Benchmarking is
comparing one's
business processes
and performance
metrics to industry
bests and best
practices from
other companies.
A benchmark is a
test that measures
the performance of
hardware, software,
or computer. These
tests can be used to
help compare how
well a product may
do against other
products.

4. BenchMark Modes
Software
vs
Hardware
Software Hardware

5. BenchMark Issues
▪ Cheating tests
▪ Results interpretation
▪ Private interests
▪ Components interaction
▪ Virtualization

6. BenchMark in
software

7. Performance Issues
▪ Technical debts
▪ Data loss
▪ Inconsistent data
▪ Functionality Risks
▪ Customers unhappy

8. Performance Issues Causes
▪ Architecture Issues
▪ Third-party components
▪ Bad routines
▪ Loading data

10. When is benchmark important?
▪ Generic component
▪ Complex routines or methods
▪ Full efficient is required

11. Companies
▪ Standard Performance Evaluation
Corporation
(https://www.spec.org/)
▪ Coremark
(https://www.eembc.org/index.php)

12. DEMOS!

13. BENCHMARKDOTNET
is a powerful .NET
library for
benchmarking.
https://benchmarkdotnet.org

14. class Program
{
static void Main(string[] args)
{
var summary = BenchmarkRunner.Run<BenchMark>();
Console.ReadLine();
}
}
public class BenchMark
{
[Benchmark]
public int RandomNumber()
{
Return new Random().Next();
}
}
Example
