Is printing a log a time-consuming operation？

[ziqiangai]

I just constructed the log object in vertxroute under the quarkus IO thread project, and entered a word in the greetings method, which reduced the throughput of the program by nearly ten times.
Is my way of logging incorrect?

@Singleton
public class VertxRoute{
    private static final Logger logger = LoggerFactory.getLogger(VertxRoute.class);
    @Inject
    Validator validator;

    final MessageService messageService;

    public VertxRoute(MessageService messageService) {
        this.messageService = messageService;
    }

    @Route(path = "/hello/:name", methods = HttpMethod.GET)
    void greetings(RoutingExchange ex) {
        logger.info("receive");
        Set<ConstraintViolation<RequestWrapper>> violations = validator.validate(new RequestWrapper(ex.getParam("name").get()));
        if( violations.size() == 0) {
            ex.ok(messageService.sayHello(ex.getParam("name").orElse("world")));
        } else {
            StringBuilder vaidationError = new StringBuilder();
            violations.stream().forEach(violation -> vaidationError.append(violation.getMessage()));
            ex.response().setStatusCode(400).end(vaidationError.toString());
        }
    }

 ....
}
