网关性能测试

注意：记得关闭限流功能

测试环境

• 测试工具：wrk，安装教程
• 服务器：CentOS7（虚拟机，宿主机：macbookpro），内存：2G，CPU:1，核数：2核
• 运行环境：Java8、Mysql-5.7、Nacos-1.1.3
• 网关启动参数：

-verbose:gc -XX:+PrintGCDetails -XX:+PrintHeapAtGC -Xloggc:gc-zuul.log \
      -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m -Xms1024m -Xmx1024m -Xmn512m -Xss256k -XX:SurvivorRatio=8 \
      -XX:+UseConcMarkSweepGC

• zuul配置（仅针对zuul，Spring Cloud Gateway没有做优化配置）：

# 不校验时间，这样一个链接可以一直进行测试
sop.api-config.timeout-seconds=0
sop.restful.enable=true

logging.level.com.gitee=info

# zuul调优
zuul.host.max-per-route-connections=5000
zuul.host.max-total-connections=5000
zuul.semaphore.max-semaphores=5000

ribbon.ReadTimeout=5000
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=13000

logging.file=sop-gateway.log

CentOS允许最大连接数

$ ulimit -n
65535

调用开放接口

• wrk命令：

wrk -t8 -c200 -d30s "http://10.1.31.227:8081/?charset=utf-8&biz_content=%7B%22name%22%3A%22%E8%91%AB%E8%8A%A6%E5%A8%83%22%2C%22id%22%3A%221%22%7D&method=alipay.story.get&format=json&sign=RjK%2FThnzAJQOw%2BfoVLS18PgWZAR%2B25SI2XdONFhS%2BmS8vsv2jNT3rygFoh%2ByX1AJbMgIEfcBzkQyqrs29jjd5dcwHVkcf7vxXshyfcEgl0fbMF6Ihycnz7rqSqkW3lzAWx4NuWUfkPnTX8Ffuf%2BhYRaI0NCpNv%2FV300HvsvmUjS6ZzS4YHaT1peSq0agfUhwRPd97aYMnUwRZDzxNfc5wuXA7OQ1o%2FPYIuIb%2FajVfwNP5ysitc%2FKtYEqt9rNAuzkcFmsw71d2RRnrPLsDN%2BuBXnIEh482f%2FbMj2Rj4%2FMq%2B0PEtlTRbg3rYnxyfowymfX%2BNmI4gNRUt70D4a%2FL3Qiug%3D%3D&app_id=2019032617262200001&sign_type=RSA2&version=1.0&timestamp=2020-01-19+13%3A34%3A12"

综上所述，Spring Cloud Gateway在没有优化的情况下，压测表现比zuul好，但zuul的数据表现也不差，但是出现超时现象，总的来说还是Spring Cloud Gateway具有优势。
