Course Introduction：Apache performance bottleneck inspection needs to start from four aspects: MPM mode, log analysis, Server-status monitoring and module loading. 1. Check and adjust the MPM mode, and reasonably set parameters such as MaxRequestWorkers based on memory; 2. Position slow requests and high-frequency errors through access and error logs; 3. Enable Server-status page to monitor connection status and CPU usage in real time; 4. Disable unnecessary loading modules to reduce resource overhead. During optimization, the effect should be adjusted item by item and observed to ensure that the configuration matches the actual load requirements.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
