In recent years, golang has become a very popular programming language, and many developers are using it to develop various applications. However, there is a question that has been bothering people, that is, how fast is golang? Below, we will discuss this issue.
First of all, we need to know the advantages of golang. Compared with other programming languages, golang has the characteristics of lightweight, high concurrency, and high efficiency. When dealing with high concurrency and large-scale requirements, golang has become the first choice of many developers. This is due to the concurrency mechanism naturally supported by golang, such as goroutine, etc., which has extremely high efficiency and performance advantages in concurrent execution.
Secondly, we need to know the performance of golang. In fact, the performance of golang will vary in different scenarios, but overall, golang has very good performance. Below, we will list some actual test data as a reference.
- Network processing performance test
In terms of network processing, golang's performance is very excellent. The following is a set of test data, which are the performance of golang, node.js, Python and other languages when processing HTTP requests. The tool used for the test is ApacheBench, the test time is 10 seconds, and the number of concurrent requests is 1000:
| Language | Response time (ms) | Number of requests |
|---|---|---|
| 184 | 47696 | |
| 1027 | 3775 | |
| 8076 | 1102 |
- CPU-intensive test
| Calculation time | |
|---|---|
| 3.4s | |
| 10.4s | |
| 4000.47s |

How to use the 'strings' package to manipulate strings in Go step by stepMay 13, 2025 am 12:12 AMGo's strings package provides a variety of string manipulation functions. 1) Use strings.Contains to check substrings. 2) Use strings.Split to split the string into substring slices. 3) Merge strings through strings.Join. 4) Use strings.TrimSpace or strings.Trim to remove blanks or specified characters at the beginning and end of a string. 5) Replace all specified substrings with strings.ReplaceAll. 6) Use strings.HasPrefix or strings.HasSuffix to check the prefix or suffix of the string.
Go strings package: how to improve my code?May 13, 2025 am 12:10 AMUsing the Go language strings package can improve code quality. 1) Use strings.Join() to elegantly connect string arrays to avoid performance overhead. 2) Combine strings.Split() and strings.Contains() to process text and pay attention to case sensitivity issues. 3) Avoid abuse of strings.Replace() and consider using regular expressions for a large number of substitutions. 4) Use strings.Builder to improve the performance of frequently splicing strings.
What are the most useful functions in the GO bytes package?May 13, 2025 am 12:09 AMGo's bytes package provides a variety of practical functions to handle byte slicing. 1.bytes.Contains is used to check whether the byte slice contains a specific sequence. 2.bytes.Split is used to split byte slices into smallerpieces. 3.bytes.Join is used to concatenate multiple byte slices into one. 4.bytes.TrimSpace is used to remove the front and back blanks of byte slices. 5.bytes.Equal is used to compare whether two byte slices are equal. 6.bytes.Index is used to find the starting index of sub-slices in largerslices.
