Rate limit Gatling-grpc user outbound requests/second

php Editor Banana In this article, we will introduce the rate limiting function in Gatling-grpc, which is used to limit the number of outbound requests sent to the user per second. Gatling-grpc is a performance testing tool that can simulate multiple concurrent users to stress test gRPC services. By using the rate limiting feature, you can control the frequency of user requests to better simulate real user behavior and network environments. This article will introduce in detail how to set the rate limit in Gatling-grpc, and how to adjust and optimize it according to your needs.

Question content

Rate limit Gatling-grpc user outbound requests/second We are developing a critical project and performing load testing using the https://www.php.cn/link/b259a593d2ac9619df8c8a5a6c2717a2 framework for GRPC specific services. We are trying to limit the number of outbound requests from gattle GRPC users, e.g. only 1 request per second. Currently, each GRPC user is making over 500 requests per second as part of our testing.

According to the Gattle documentation https://gadling.io/docs/gadling/reference/current/core/scenario/, we can take advantage of the speed of normal http requests, e.g. forever().on( Pace(5) .exec( // Will run every 5 seconds, no matter what pause time is used pause(1, 4) ) );

It would be nice to have this speed-like method for gatling-grpc as well, so that we can throttle our GRPC clients.

There is currently no clear solution in mind. Is there any workaround in gadling-grpc on how to limit outbound requests per second for GRPC users?

Try using the pace method in our gadling-grpc java client code.

Workaround

I think this issue is fixed as shown below, so add Gatling speed to this Gatling grpc. Basically, pass pace to forever.on()

I'm using this gattle grpc client:
https://www.php.cn/link/b259a593d2ac9619df8c8a5a6c2717a2

private final ScenarioBuilder myScenario =
    scenario("InboundGrpcScenario")
        .forever()
        .on(pace(6).exec(inboundHydration()));
