Assignee: Sean Li
> QPS rate limit bug
> ------------------
>
> Key: SCB-651
> URL: https://issues.apache.org/jira/browse/SCB-651
> Project: Apache ServiceComb
> Issue Type: Bug
> Components: Java-Chassis
> Affects Versions: java-chassis-1.0.0-m1
> Reporter: Sean Li
> Assignee: Sean Li
> Priority: Major
> Attachments: limit value as 1.jpeg, limit value as 2.jpeg
>
>
> When setting _servicecomb.flowcontrol.Provider.qps.limit.[ServiceName]_, the
> actual number of requests allowed per second is always 1 less than the limit
> value.
> For example, if I set _flowcontrol.Provider.qps.limit._
> _business-service-consumer_ as 1, I'll get NO successful request at the very
> beginning, although I would expect 1 successful request instead of none.
> Similarly, if I set _flowcontrol.Provider.qps.limit._
> _business-service-consumer_ as 2, I'll get 1 successful request instead of 2.
>
> However, if I pause before sending requests, for example add
> _Thread.sleep(100)_ before invoking the first request, the number of requests
> allowed per second will be correct this time. (i.e. 1 successful request when
> limit value is 1, 2 successful requests when limit value is 2, etc.)
