Benchmarking "Homebrew via Barrel" against Homebrew

Barrel ultimately is a tool which invokes brew commands in a shell. In doing so, it tries to make sure that its own overhead is negligible. I ran a few benchmarks using hyperfine on a Macbook Air (2020), M1 with target architecture x86_64, and the results indicate that using Homebrew via Barrel is virtually indistinguishable from using Homebrew directly. Networked and disk I/O intensive brew commands are not used for benchmarking due to their inherent unpredictability during execution.

Configuration used:

Homebrew:

macOS: 12.5-x86_64
HOMEBREW_VERSION: 3.5.8
HEAD: ff9c2500195cc357d4a06f99d462f8d8a5d37892
Homebrew Ruby: 2.6.8
CPU: octa-core 64-bit westmere

Homebrew via Barrel (Ext):
