Hello, With the rate limiting module you can easily rate limit based on seconds or on minutes. What I would like to do however is rate limit based on a 100 millisecond or 10 millisecond interval. That way you do not have a burst of requests at the beginning of a second. But a more continuous flow of requests. Is this possible with nginx? If not can anyone point me to the right location in the source where the rate limiting is actually done. (I assume it has something to do with ngx\_http\_limit\_req\_lookup in ngx\_http\_limit\_req\_module.c) Thanks in advance, Pieter Posted at Nginx Forum: > **[Rate limiting intervals](https://forum.nginx.org/read.php?2,246575,246575#msg-246575)** > > Hello, With the rate limiting module you can easily rate limit based on seconds or on minutes.

There is no second/minute granularity in limit\_req module. It’s just a measure. If you set 100r/s with zero burst, then every request received in less than 10 milliseconds after the previous permitted one will be declined. wbr, Valentin V. Bartenev ---

Hi Valentin, Thanks for the info. That indeed does seem to work as you mention. I have to figure out what else is going wrong then.

Hi Valentin, I know that 100r/s is equal to 1 request per 10 milliseconds. If you specifiy 100r/s nginx will send 100 requests within the first milliseconds of a certain second. Once these request are done no request will be handled anymore. When you would be able to specifiy more granular rate limiting interval you whould be able to get a more continuous load. see: [Startseite - imagebin.org](http://imagebin.org/287286) Kind regards, Pieter Posted at Nginx Forum: > **[Re: Rate limiting intervals](https://forum.nginx.org/read.php?2,246575,246578#msg-246578)** > > Hello, With the rate limiting module you can easily rate limit based on seconds or on minutes.
