/** # 脚本说明
|
||||
* 压测发射器(在 37 服务器以 root 运行):
|
||||
* 从 pool.json 逐个(并发 workers)执行:
|
||||
* 节点导入(幂等)→ POST lease(ttlMs=2h,规避 10 分钟空闲自动关闭)
|
||||
* → POST browser/start → 按标签数经 CDP /json/new 开真实页面。
|
||||
* 直到「资源耗尽」触发:MemAvailable<1.5GB / swap已用≥7.2GB /
|
||||
* 连续启动失败≥10 / 已开浏览器被 OOM 杀≥10 / 达到 --max 封顶。
|
||||
* 触发后停止发射(已开浏览器保持常驻),结论写 data/<label>-stop.json。
|
||||
* 断点续跑:进度在 data/<label>-launched.jsonl,重启脚本会跳过已开指纹。
|
||||
*
|
||||
* 用法:bun run-stress.ts --pool data/pool.json --tabs 3 --label test1 [--max 500] [--concurrency 6]
