Master Java – a must-have language for software development, Android apps, and more! ☕️ This beginner-friendly course takes you from basics to real coding skills.
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.
特征工程+
https://www.ibm.com/think/topics/feature-engineering
Feature engineering preprocesses raw data into a machine-readable format. It optimizes ML model performance by transforming and selecting relevant features.

Better features make better models. Discover how to get the most out of your data.
Perf+
https://perfwiki.github.io/main/
perf is powerful: it can instrument CPU performance counters, tracepoints, kprobes, and uprobes (dynamic tracing).
https://www.brendangregg.com/bpf-performance-tools-book.html
This book can help you get the most out of your systems and applications, helping you improve performance, reduce costs, and solve software issues.
[英文] perf Examples
https://www.brendangregg.com/perf.html
These are some examples of using the perf Linux profiler, which has also been called Performance Counters for Linux (PCL), Linux perf events (LPE), or perf_events.

pprof+
https://go.dev/blog/pprof
At Scala Days 2011, Robert Hundt presented a paper titled Loop Recognition in C++/Java/Go/Scala.

I have been working with Go for the better part of the year, implementing a scalable blockchain infrastructure at Orbs, and it’s been an exciting year.
