Tuning Arachni for lowering requests per second

I calculated an effective rate around 7 request per second from the Arachni scanner , which is a lot for ta server (normal peak is around 1 req per second). I think it could handle 2-3 req/sec based on the graphs from recent history.

What's the best way to reduce Arachni requests per second.

    You can't get that sort of rate limiting (at least not yet) but you can reduce concurrency which would result in less requests per second.

    The lowest you can get is --http-request-concurrency=1 --browser-cluster-pool-size=1.
    This means that the scan will only keep one connection active at any given time and only one browser will be used for the scan -- browsers run in parallel.

    Keep in mind though that the scan will take a very long time, maybe too long to be usable.
    It would be better if you setup a separate, better performing server just for testing.
