## プロジェクトの歴史と使われ方

MBW is a compact command-line memory bandwidth benchmark. It times copies between large in-memory arrays to provide a quick estimate of available memory throughput.

### プロジェクトの歴史

The upstream manpage is dated April 2006, while the GitHub repository was imported in March 2012. The repository has maintained a small tagged release series through v2.0, reflecting the project's long-lived, single-purpose design.

### 採用の歴史

The supplied package metadata records MBW packages for Homebrew, Debian, and Ubuntu. This modest cross-platform distribution suits a small benchmark intended for quick local checks rather than a comprehensive profiling suite.

### 使われ方

Users give mbw an array size in MiB and may select tests for memcpy, a simple element-by-element copy, or arbitrary-block copies. The manpage advises avoiding paging and busy systems so the reported throughput better represents memory copying.

### パッケージ好きにとっての重要性

MBW appeals to package users because it is easy to build, easy to audit, and quick to invoke when a full benchmark suite would be excessive.

### タイムライン

- 2006: The upstream manpage documents MBW's benchmark interface.
- 2012: The code is imported into the public GitHub repository and v1.2 is tagged.
- 2022: v1.5 is tagged.
- 2023: v2.0 is tagged.

### Related projects

- MBW occupies the same package niche as small memory and system benchmarks such as STREAM and lmbench, while remaining focused on copy throughput.
