# 1、测试工具 #

## 1.1、Apache JMeter 5.1.1 ##

Apache JMeter是Apache组织开发的基于Java的压力测试工具。

## 1.2、Java VisualVM 1.8 ##

VisualVM 是一款免费的，集成了多个 JDK 命令行工具的可视化工具，它能为您提供强大的分析能力，对 Java 应用程序做性能分析和调优。这些功能包括生成和分析海量数据、跟踪内存泄漏、监控垃圾回收器、执行内存和 CPU 分析，同时它还支持在 MBeans 上进行浏览和操作。本文主要介绍如何使用 VisualVM 进行性能分析及调优。

# 3、参数调整 #

## 3.1、Spring cloud zuul yml 参数调整（具体值参数值需要参考实际环境） ##

spring:
      application:
        name: zuul
      profiles:
        active: dev
      datasource:
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://localhost:3306/test?characterEncoding=utf-8&serverTimezone=UTC&useSSL=true
        username: root
        password: 1156543
      jpa:
        hibernate:
          ddl-auto: create
        show-sql: true
      redis:
        host: localhost
        port: 6379
        password: 1654
    eureka:
      client:
        serviceUrl:
          defaultZone: http://eureka:8761/eureka/
        fetch-registry: true
        register-with-eureka: true
      instance:
        prefer-ip-address: true
    server:
      tomcat:
        max-threads: 1000
        min-spare-threads: 64
        max-connections: 2000
    zuul:
      host:
        connect-timeout-millis: 300000
        socket-timeout-millis: 300000
      sensitive-headers:
    hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 6000
    management:
      endpoints:
        web:
          exposure:
            include: "*"
    zuul.host.maxTotalConnections: 2000
    zuul.host.maxPerRouteConnections: 20
    zuul.semaphore.max-semaphores: 2000

# 4、测试结果 #

Spring cloud zuul 使用 Hystrix 默认执行方式 SEMAPHORE（信号量）

## 4.1、并发1000测试 ##

tomcat设置 max-threads: 1000，同时并发请求1000次，zuul的线程数量接近1000，全部返回成功，没有出现异常
