var bench = common.createBenchmark(main, {
size: [16, 512, 1024, 4096, 16386],
millions: [1]
});

function main(conf) {
var iter = (conf.millions >>> 0) * 1e6;
var size = (conf.size >>> 0);
var b0 = new Buffer(size).fill('a');
var b1 = new Buffer(size).fill('a');

b1[size - 1] = 'b'.charCodeAt(0);

Please insert code to force optimization of b0.compare before starting the benchmark. Take a look at some of the other (e.g. path) benchmarks to see how to do this.

bench.start();
for (var i = 0; i < iter; i++) {
b0.compare(b1);
}
bench.end(iter / 1e6);
}
