总结

总时间上来,差别不大,webmvc是26.244 seconds,而webflux是26.269 seconds,启动线程差别很大,webmvc最高峰时118个,webflux一直是47个。 其它CPU和堆的使用也差别不大。

使用undertow做嵌入式服务的spring mvc , 用时26.177 seconds,可以看出undertow性能上面的确比tomcat要强。

实验步骤

1. spring_web_mvc 项目

pom.xml


	org.springframework.boot
	spring-boot-starter-web

Spring boot application类

@SpringBootApplication
public class SpringWebMvc {
    public static void main(String[] args) {
        SpringApplication.run(SpringWebMvc.class, args);
    }
}

RestController

@RestController
public class SyncController {
    @GetMapping("/sync_result")
    public String getResultAsyc(HttpServletRequest request) {
    	try {
			Thread.sleep(500);
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
    	return "Result is ready! threadName:" + Thread.currentThread().getName();
    }
}

项目启动之后,运行jvisualvm.exe监控Thread,CPU,Heap..

用CMD运行下面命令启动apache ab,开始压力测试

ab -n 5000 -c 100 localhost:8080/sync_result

apache ab运行结果

2. spring_webflux 项目 

pom.xml

   		
			org.springframework.boot
			spring-boot-starter-webflux
		

application class

@SpringBootApplication
public class SpringWebFlux {
    public static void main(String[] args) {
        SpringApplication.run(SpringWebFlux.class, args);
    }
}

RestController

@RestController
public class WebFluxController {

    @GetMapping("/flux_result")
    public Mono getResult(ServerHttpRequest request) {
       return Mono.defer(() -> Mono.just("Result is ready!" + Thread.currentThread().getName()))
         .delaySubscription(Duration.ofMillis(500));
    }
}

压力测试的运行结果

 webflux 会根据cpu的数量启动线程。我CPU信息:内核:8,逻辑处理器:16。

3. 利用undertow做嵌入式服务的spring mvc 

在spring mvc的项目的基础上做以下修改

		
			org.springframework.boot
			spring-boot-starter-web
			
                
                    org.springframework.boot
                    spring-boot-starter-tomcat
                
            
		
		
            org.springframework.boot
            spring-boot-starter-undertow
        

运行 

ab -n 5000 -c 100 localhost:8080/sync_result

Concurrency Level:      100
Time taken for tests:   26.177 seconds
Complete requests:      5000
Failed requests:        0
Total transferred:      755000 bytes
HTML transferred:       80000 bytes
Requests per second:    191.01 [#/sec] (mean)
Time per request:       523.532 [ms] (mean)
Time per request:       5.235 [ms] (mean, across all concurrent requests)
Transfer rate:          28.17 [Kbytes/sec] received

              min  mean[+/-sd] median   max
