Which one has better performance, erlang or golang?
There are performance differences between Erlang and Go. Erlang excels at concurrency, while Go has higher throughput and faster network performance. Erlang is suitable for systems that require high concurrency, while Go is suitable for systems that require high throughput and low latency.
Performance comparison between Erlang and Go
Erlang and Go are both high-performance programming languages for building concurrent and Distributed Systems. While both have their advantages, they have some key differences in performance.
Concurrency:
- Erlang is born for concurrency, and its process model provides a lightweight and efficient concurrency mechanism.
- Go implements lightweight threads through Goroutine and also has excellent concurrency.
Memory management:
- Erlang uses garbage collection algorithms for memory management, which is excellent at reducing memory leaks and improving program robustness.
- Go uses a reference counting garbage collection mechanism, which is generally faster than Erlang's garbage collection mechanism.
Network Performance:
- Erlang has a long history in network performance, with its OTP-based Erlang Distributed Protocol (EDP) providing efficient and reliable network communication.
- Go's network library is high-performance and easy-to-use, supporting various network protocols.
Benchmark test:
Specifically, there are the following differences in the performance of Erlang and Go in different benchmark tests:
- TechEmpower Web Benchmark: Go has better throughput and latency than Erlang in most cases.
- SPECjbb2015 Benchmark: Erlang performs better for concurrent transaction processing workloads.
- Redis Benchmark: Go is generally faster than Erlang for both read and write operations.
Application scenarios:
- Erlang: Suitable for systems that require a high degree of concurrency, fault tolerance and reliability, such as Telecom networks, financial systems and embedded systems.
- Go: Ideal for network-intensive and parallel systems that require high throughput, low latency, and ease of use, such as web servers, microservices, and distributed computing.
Ultimately, the best choice depends on the specific application scenario and performance requirements. Erlang's concurrency advantages make it well-suited for systems that need to handle large numbers of concurrent connections or transactions, while Go's high throughput and low-latency characteristics make it suitable for systems that need to handle large amounts of network traffic.

Golang framework vs. Go framework: Comparison of internal architecture and external features
Jun 06, 2024 pm 12:37 PM
The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.
