<div>Hi there,</div>
<div> </div>
<div>> I might have misunderstood some concepts and rectify them here:</div>
<div>> burst--bucket size;</div>
<div> </div>
<div>Yes.</div>
<div> </div>
<div>> rate--water leaks speed (not requests sent speed)</div>
<div> </div>
<div>Yes.</div>
<div> </div>
<div>The server can control how long it waits before starting to process a</div>
<div>request (rate) and how many requests it will process quickly (burst). It</div>
<div>cannot control when the requests are sent to it.</div>
