Benchmarks

Suppose you need to deploy a lot of mock APIs for your service.

Let's determine how many APIs you can deploy without any noticeable performance degradation.

I tested on a MacBook Pro 16" with these characteristics:

• 2.6 GHz 6-Core Intel Core i7;
• 16 GB 2667 MHz DDR4;
• Intel UHD Graphics 630 1536 MB.

For testing we will choose a simple mock, which we will request from each mock API. We will send requests using the ab utility. An example of such a mock:

{
    "request" : {
        "urlPath" : "/HealthCheck",
        "method" : "GET"
    },
    "response" : {
        "status" : 200,
        "body" : "success",
        "headers" : {
            "Content-Type" : "application/json"
        }
    }
}

Command to run tests:

ab -c 10 -n 100 "http://wiremock:${PORT}/HealthCheck"

Test parameters:

• the number of requests is 100;
• 10 requests can be executed simultaneously.

Test Scenario:

• preparing N Wiremock Standalone processes;
• waiting for all processes to be ready to serve clients;
• running the ab utility for all processes simultaneously.

Results:

In the graph you can see that with the addition of a Wiremock instance, the maximum response time doubles.
