the CPU, so the CPU is a computer's soul and core. And the response CPU speed of the basis is the frequency, the higher the frequency, the CPU processing data faster. And the core frequency is when starting a running program, the processor will automatically accelerate to the appropriate frequency, and the original speed will enhance the 10%~20% to ensure the smooth operation of a program of technology. Here is the latest CPU performance ladder chart, and you can choose the CPU you want based o

the Micro CLI Toolkit. This micro toolkit provides features such as API gateways, Sidecar, Web proxies, and other cool features. But the main feature we use in this article is the API gateway. The API Gateway will allow us to call the RPC proxy as a Web-friendly Javascripton RPCCalled, and then exposes the URLs used in the client application. So how do these cool features work? First, make sure that the Micro Toolkit is installed: ' $ go get-u github.com/micro/micro ' in a better way to use mic
