.net core下，Ocelot网关与Spring Cloud Gateway网关的对比测试

有感于 myzony 发布的针对 Ocelot 网关的性能测试，并且公司下一步也需要对.net和java的应用做一定的整合，于是对Ocelot网关、Spring Cloud Gateway网关做个了对比测试，使用了wrk进行测试

.net core + Spring Cloud Gateway 是使用 steeltoe 工具接入注册中心Spring Cloud Eureka，共Spring Cloud Gateway调用

应用服务器环境 windows server 2008 .net core 2.2 java 1.8

172.16.1.65 部署 Ocelot的.net core接口-6002、Spring Cloud Gateway的spring boot接口-9004、Spring Cloud Gateway的.net core接口-9001

172.16.1.68 部署 Ocelot的.net core接口-6004、Spring Cloud Gateway的spring boot接口-9004、Spring Cloud Gateway的.net core接口-9001

172.16.1.120 部署 Ocelot网关-6000、Spring Cloud Eureka注册中心-7000 + Spring Cloud Gateway网关-8000

测试工具 wrk 参数统一为 -t 50 -c 10000 -d 60s --latency --timeout 3s

测试服务器环境 centos 7.5 172.16.1.144，并根据 wrk的报错修改了最大打开文件数限制

测试结果汇总如下图

可以看出Ocelot的总请求数、QPS比Gateway高不少，而且超时数也少，但是平均响应时间要比Gateway高不少。

总体上来说，两者基本上处于同一水平，对于一般的企业业务系统足够了，因为上面的测试的都没有涉及业务处理，系统瓶颈不应该是在网关。

考虑我们公司的实际情况，倾向使用 .net core+spring cloud gateway，这样大家各自做各自的，只需要做好接入就好了。

.net core 所有应用，在Startup中关闭日志

public void ConfigureServices(IServiceCollection services)
        {
            services.AddLogging(op => op.ClearProviders());
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }

Ocelot 网关，在Startup中关闭日志，注释掉mvc的注入和使用

public void ConfigureServices(IServiceCollection services)
        {
            services.AddLogging(op => op.ClearProviders());
            services.AddOcelot(Configuration);

            //services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            app.UseOcelot().Wait();

            //app.UseMvc(routes => {
            //    routes.MapRoute(
            //        name: "default",
            //        template: "{controller=Home}/{action=Index}/{id?}");
            //});
          
        }
