<div>A request is one line in the access log I assume, typically a html verb like "get". I use a single core VPS, so I don't have much CPU power. Unless the verb action is trivial, I doubt I would hit 2000/s. From experimentation, a burst of 10 gets the images going mostly unimpeded, and a rate of 10/s is where you see a page just start to slow down. I think a rate of 2000/s isn't much of a limit. </div>

<div>> Why excess: 101.000? I set it as 2000r/s ?</div>
<div> </div>
<div>You've configured "burst=100", and nginx starts to reject requests </div>
<div>when the accumulated number of requests (excess) exceeds </div>
<div>the configured burst size.</div>
<div> </div>
<div>In short, the algorithm works as follows: every request increments </div>
<div>excess by 1, and decrements it according to the rate configured. If </div>
<div>the resulting value is greater than burst, the request is </div>
<div>rejected. You can read more about the algorithm used in </div>
<div>Wikipedia, see https://en.wikipedia.org/wiki/Leaky_bucket.</div>
