Newbie question about benchmark.js

http://benchmarkjs.com/docs#prototype_cycles maybe?

You can specify the minSamples to collect, the default is 5, but you can't specify how many times an operation should run, benchmark.js handles that for you. It automatically repeats a test until it reaches the minimum time needed to take an accurate measurement (usually ~50ms).

Thanks. Perhaps I'm not doing this correctly, but say I'm testing two linked list implementations and I need both to do remove() the exact same amount of time (beyond that they'd be removing nothing), how would I do that?

[jdalton]

The setup, teardown, and fn have access to the repeat count via this.count.

So in your setup you would add this.count number of items, then in your fn you would call lib.remove(item). That way when lib.remove(item) is called this.count times it will remove exactly how many are added in the setup. The setup is not counted against the time of the fn.

That's what I was searching for, thanks.
