软件包摘要
Memory Bandwidth Benchmark
历史
项目历史与用法
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.
项目历史
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.
采用历史
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.
使用方式
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.
为什么软件包爱好者会关心
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.
时间线
- 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.
