Java Benchmark Tool
2+
===================
3+
4+
This tool is designed to benchmark the performance of the host it is running on. It will monitor the speed of CPU, RAM and disk.
5+
6+
7+
Download
8+
--------
9+
10+
The binary package is available from the [release page](https://github.com/w4software/misc-tool-benchmark/releases)
11+
12+
13+
The source package can be obtained either as a [zip archive] or using git
14+
15+
git clone https://github.com/w4software/misc-tool-benchmark
16+
17+
18+
Usage
19+
-----
20+
21+
To start the benchmark, run the following command
22+
23+
java -jar misc-tool-benchmark-1.0.jar [number of threads]
24+
25+
The parameter _number of threads_ is optional. If not provided, the benchmark
26+
will try to determine the number of real cpu cores instead of relying on the
27+
OS determined value that is a number of cpu threads (that may be different when hyperthreading-like features are in enabled).
28+
29+
As a starter, you may want to begin with a _number of thread_ of __1__ before
30+
trying to test performance in parallel processing.
31+
32+
The overall process should usually take a couple of minutes on modern platforms.
33+
34+
35+
Tests
36+
-----
37+
38+
Following tests are run during the benchmark
39+
40+
41+
### CPU Tests
42+
- CPU32: Make some mathematical computation using 32-bit integers
43+
- CPU64: Make some mathematical computation using 64-bit integers
44+
- Float32: Make some mathematical computation using 32-bit precision floating point numbers
45+
- Float64: Make some mathematical computation using 64-bit (double) precision floating point numbers
46+
47+
48+
### RAM Tests
49+
50+
- RAM: Make copy from memory to memory zones (total of 5 GB transfer)
51+
52+
53+
### Disk Tests
54+
55+
- SmallFile: write some 1M sized temporary files
56+
57+
58+
Results
59+
-------
60+
61+
The results will show the time taken to complete all tests so, the lower result reflect a better performance.
