Dear Gatling,

We are ran the load test for our API using atonceuser(1). In the Gatling report the response time is 1200ms always for API. But checking the logs response time is different.

For example: In log 800ms. But in the Gatling Report it is coming under above 1200ms.

How Gatling is calculating the response time.

Which logs? server logs? if so, there’s lots of differences: DNS resolution, opening TCP socket, performing TLS handshake, network time, etc…

Only for this particular API, we are always getting a response time of more than 1200ms. But for other APIs, the response time will change.
