bench-hexo

A benchmarking cli for Hexo, modified from hexo#benchmark.js

Usage

Profiling

Use 0x to generate a flamegraph for the Hexo generation process.

Syntax

Options

• --max-old-space-size <number>: Set the maximum old space size for Node.js (default: 4096MB).
• -c, --concurrency <number>: Set the number of concurrent processes (default: Infinity).
• --no-clean: Do not clean Hexo cache before profiling.

Example

✔ Cleaning complete.
✔ Profiling complete. Flamegraph saved to 0x directory.
✔ Hexo statistics loaded.
