As with anything, depends on a number of factors.

Benchmark your test scripts and work it out based on your use case.

I have test the scenario of bellow code. I am getting Connection Refused Error. I am using the Intel Xeon CPU @ 2.7GHz(2 processor) with 8gb ram.

How can i model the scenario to test the 5k request per sec. The error comes due to my hardware issue or else what is the exact problem ?

`

package LoadTesting

import java.util.concurrent.TimeUnit

import akka.util.Timeout
import io.gatling.core.Predef._
import io.gatling.core.structure.ScenarioBuilder
import io.gatling.http.Predef._
import io.gatling.http.protocol.HttpProtocolBuilder

import scala.concurrent.duration._
import scala.language.postfixOps

class LoadTest extends Simulation{
// implicit timeout for the request
val timeoutSec: Int = 10000
implicit val timeout: Timeout = Timeout(timeoutSec, TimeUnit.SECONDS)

// URL details for the request
val baseUrl: String = “http://localhost:8000”
val postUrl: String = “/ingestion”
val bodyMsg = “SampleText”
// Output status code
val statusCodeOK = 200

val httpProtocol: HttpProtocolBuilder = http
.baseURL(baseUrl)

val ingestionScn: ScenarioBuilder = scenario(“Service”)
.exec(http(“ingestion”)
.post(postUrl)
.body(StringBody(bodyMsg))
.check(status is statusCodeOK))

setUp(ingestionScn.inject(
nothingFor(2 seconds),
rampUsersPerSec(10) to 1000 during(10 seconds)

).protocols(httpProtocol))

}
