Under what circumstances does golang need to disable gc (garbage collection)?

Mar 29, 2023 pm 03:16 PM

Golang is a fast, efficient, and reliable programming language, but in some cases, it may face some problems with garbage collection (GC). In this case, disabling garbage collection may be a useful solution. In this article, we will explore some of the advantages of Golang when disabling garbage collection and the situations in which it may be necessary to disable garbage collection.

Advantages:

1. Faster execution speed

When there is no need to execute GC, the program execution speed will be faster. Therefore, disabling GC can improve the performance of Golang programs, making them faster and more responsive.

2. Avoid phased pauses

When the GC is running, the entire program will be in a stagnant state, waiting for the garbage collection program to run and clean up. This pause phenomenon is very obvious in some situations, such as when a large number of temporary objects are generated when the program is running. These objects are almost all short-term objects and will be released before the next GC run. At the same time, GC will also occupy a lot of CPU and memory resources. Disabling GC can avoid the garbage collection process in the program, thereby avoiding periodic pauses.

3. Improvement of work efficiency

Disabling GC means that the program needs to manually manage memory, which may increase the complexity of code implementation. However, this can also stimulate the creativity of engineers and enable them to learn to manage memory more professionally and efficiently, thereby improving work efficiency.

4. Better control

When GC is disabled, programmers have better control over memory allocation and release. This also provides programmers with more memory control options, making programs more controllable and reliable.

5. It has its special role in some special scenarios

Disabling GC can optimize performance in many scenarios, such as high concurrency or large-scale data set operations. In these cases, disabling GC will make it easier for the program to control memory usage and consume less performance.

Disadvantages:

1. Manual memory management

Disabling GC means that programmers need to manually manage memory, which requires more memory knowledge and skills. This may also increase the complexity of the code and increase the likelihood of code errors. In addition, manual continuous management of memory brings additional fatigue.

2. Potential memory leaks

During the period of disabling garbage collection, programmers need to manually manage memory. When errors occur in memory operations, it is easy to cause memory leaks. These leaks can cause a program's memory usage to grow indefinitely, eventually rendering the program unusable.

3. High possibility of errors

When GC is disabled, the possibility of errors increases significantly, especially when errors occur when manually managing memory. However, as engineers gain time and experience with memory operations, the incidence of this may decrease.

Under what circumstances do you need to disable GC?

1. Low-latency applications

In applications that require low latency, program response speed is very important. In such applications, disabling GC can reduce pause times and improve program responsiveness.

2. High-performance applications

In high-performance applications, GC should be reduced or avoided as much as possible, because GC may significantly affect the performance and response time of the program.

3. Small applications

In small programs, disabling GC can manage memory well, providing better performance and taking up less memory.

4. Special situations

In special scenarios, such as real-time data processing and large-scale collection processing, disabling GC will avoid additional performance consumption. In these cases, disabling GC may be necessary.

Summary:

By disabling GC, Golang programmers can improve the performance and response speed of the program, but at the same time they need to consider the risk of memory leaks and errors. In some special cases, especially in low-latency, high-performance, small applications, and other special scenarios, disabling GC may be necessary. Regardless of whether disabling GC is necessary, programmers must always pay attention to the quality and safety of their code.

What are the vulnerabilities of Debian OpenSSL What are the vulnerabilities of Debian OpenSSL Apr 02, 2025 am 07:30 AM

OpenSSL, as an open source library widely used in secure communications, provides encryption algorithms, keys and certificate management functions. However, there are some known security vulnerabilities in its historical version, some of which are extremely harmful. This article will focus on common vulnerabilities and response measures for OpenSSL in Debian systems. DebianOpenSSL known vulnerabilities: OpenSSL has experienced several serious vulnerabilities, such as: Heart Bleeding Vulnerability (CVE-2014-0160): This vulnerability affects OpenSSL 1.0.1 to 1.0.1f and 1.0.2 to 1.0.2 beta versions. An attacker can use this vulnerability to unauthorized read sensitive information on the server, including encryption keys, etc.
