In the field of software development, Golang is currently a very popular programming language. Its emergence is due to the research and development of Google. Golang is designed to improve programmers' development efficiency while also taking into account the high performance of program running. Golang not only has the advantages of safety, simplicity, and ease of learning, but also has strong multi-core processing capabilities and advanced concurrent programming models. This development language has been widely used in Internet companies, such as: Google, Uber, Dropbox, Docker, Kubernetes, etc.

However, for programmers, Golang can also be considered a "car". For car owners, they not only use the vehicle for daily use, but also modify the car in the hope of improving the performance of the car or meeting certain specific needs.

Similarly, in the field of programming languages, Golang can also be modified to achieve similar effects. The following will introduce some parts of the Golang language that are worth modifying.

  1. Garbage Collector

The garbage collector in Golang is an important feature of it. Because the garbage collector regularly cleans out memory that is no longer in use, this ensures that the program does not have problems such as memory leaks.

However, in some cases, the garbage collector in Golang may have an impact on the performance of the program. Therefore, programmers can consider modifying the garbage collector to improve performance. For example, programmers can increase the concurrency of the garbage collector, thereby reducing blocking during the recycling process and improving throughput when the program is running.

  1. Concurrency model

The concurrency model in Golang is one of its most important features. Goroutines and channels in Golang make it easy for programmers to write concurrent programs. However, if there are too many concurrent operations in the program, it will cause problems such as resource contention in the program.

Therefore, programmers can modify the concurrency model. For example, programmers can replace communication between multiple goroutines through shared memory, thereby reducing the use of channels. This approach may improve program performance, but it requires programmers to have a deep understanding of concurrent programming.

  1. IO operation

When performing IO operations, Golang is implemented by calling the io package in the standard library. However, for some high-performance IO operations, the implementation of the io package in Golang may not be good enough.

Therefore, programmers can modify IO operations. For example, you can use third-party high-performance IO libraries to improve program performance.

  1. Memory allocation

In Golang, memory allocation is implemented by the garbage collector. However, in some cases, programmers require fine-grained control over memory allocation to achieve higher performance.

Therefore, programmers can use memory pools and other means to modify memory allocation. Memory pool is a memory reuse technology that reduces memory allocation time by temporarily saving previously allocated memory in the memory pool and using it directly the next time you need to allocate memory.

Summary

By modifying Golang, the performance of the program can be improved and the advantages of Golang can be fully utilized. However, the modification process requires programmers to have in-depth understanding and practical experience of Golang. Programmers need to make judgments and choices based on actual situations to achieve optimal performance.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
