I send request to webflux demo server. use springboot version 2.4.1 ,I can not find reason why create so many boundedElastic-evictor thread and always keep timed waiting status.
ab -n 10000 -c 1000 -T "application/x-www-form-urlencoded" -p test.txt http://127.0.0.1:8080/router/rest/1
controller code:
@RestController
@RequestMapping("/router/rest")
public class BaseController {
@RequestMapping("1")
public Mono<String> mono(){
return Mono.just("111");
}
}
webflux lots of boundedElastic-evictor TIMED_WAITING make memory up obvious.
