This could just be 2e5?

Yeah. There are a couple like this in the benchmark suite. I'll update those all separately.

statType: ['fstat', 'lstat', 'stat']
});

async function run(n, statType) {
const arg = statType === 'fstat' ?
await fs.promises.open(__filename, 'r') : __filename;
let remaining = n;
bench.start();
while (remaining-- > 0)
await fs.promises[statType](arg);
bench.end(n);

if (typeof arg.close === 'function')
await arg.close();
}

function main(conf) {
const n = conf.n >>> 0;
const statType = conf.statType;
run(n, statType).catch(console.log);
}
