性能调优+
https://goperf.dev/
The Go App Optimization Guide is a series of in-depth, technical articles for developers who want to get more performance out of their Go code without relying on guesswork or cargo cult patterns.
https://web.dev/learn/performance
This course is designed for those new to web performance, a vital aspect of the user experience.
https://www.ibm.com/think/insights/application-performance-optimization
Application performance is not just a simple concern for most organizations; it’s a critical factor in their business’s success.
https://www.oreilly.com/library/view/optimizing-java/9781492039259/
Performance tuning is an experimental science, but that doesn’t mean engineers should resort to guesswork and folklore to get the job done.
RPC+
https://javaguide.cn/distributed-system/rpc/rpc-intro.html
为什么要 RPC ? 因为,两个不同的服务器上的服务提供的方法不在一个内存空间,所以,需要通过网络编程才能传递方法调用所需要的参数。并且,方法调用的结果也需要通过网络编程来接收。

This video is part of an 8-lecture series on distributed systems, given as part of the undergraduate computer science course at the University of Cambridge.
