Speed up integeration tests withVirtualTime - stream of Flux.range with .delayElements

Question

I have Controller that returns Flux of Strings - basically returns stream of data (Strings containing current time), Strings are delayed 1 second using on .delayElements(Duration.ofSeconds(1)) on Flux

Controller:

    @GetMapping(value = "/currentTimeReactiveFlux", produces = MediaType.TEXT_EVENT_STREAM_VALUE)
@ResponseBody
public Flux<String> exampleOfFluxDeleyedResponse() {

    return Flux.range(1, 1000)
            .delayElements(Duration.ofSeconds(1))
            .map(integer -> "Current time (1) is " + OffsetDateTime.now())
            .doOnNext(s -> log.info("S: " + s + " -> " + LocalDateTime.now().getSecond()))
            .doOnCancel(() -> log.info("Cancelled"));
}

Is it possible to speed up this in Integration tests with WebClientTest. This is working slowly ( delays):

Controller integration test:

 @Autowired
    WebTestClient webTestClient;

   @Test
    void testSpeedUpStreamsOfFlux() {
        FluxExchangeResult<String> result = webTestClient.get().uri("/currentTimeReactiveFlux")
                .accept(MediaType.TEXT_EVENT_STREAM)
                .exchange()
                .expectStatus().isOk()
                .returnResult(String.class);

        Flux<String> eventFlux = result.getResponseBody();

        StepVerifier.withVirtualTime(()-> eventFlux)
                .expectNextCount(10)
                .thenAwait(Duration.ofSeconds(10))
                .thenCancel()
                .verify();
    }
