Why is go more performant than php?

In the projects I work on, my main development language is PHP. Due to needs or to make up for the shortcomings of PHP, I need to make various extensions for PHP. For example, PHP itself does not support threads, queues, and processes. It cannot be used in a production environment. It can be said that PHP does not have any "process", so there are many articles on the Internet explaining how to implement PHP queues, multi-threading, etc. In my understanding, instead of using PHP itself to implement this feature that cannot guarantee robustness , it is better to explore and use some languages ​​that are integrated and perform well.

I learned about the golang language on Weibo. The syntax of golang is similar to C and python. Students with experience in these two languages ​​will get started more smoothly! The advantages of the golang language are here. I won’t explain them one by one! !
After studying for a period of time, the maintenance business happened to encounter a bottleneck. In addition, because the business I maintained belonged to the interface layer, the logic was relatively simple and only json data was output, so I started to use golang to reconstruct the existing system. The transformation is in progress. Because some colleagues are skeptical about golang, and most of the online performance comparisons are just hello word output, which has little reference significance, I used two online intranet machines to make a formal business performance comparison between PHP and golang

Server configuration: 16-core E5620 @ 2.40GHz 11G memory
Business includes: DB (oracle) and redis query. When there is cache, DB will no longer query and directly read redis, querying two primary keys in batches

Use apache's ab test to concurrently test 200, 20,000 requests

golang concurrency test
Golang's qps is about 9675/s, the highest is about 10200/s, cpu utilization The peak rate is around 10.6%. Golang has enabled multi-core and maintained 40 redis connection pools

The above php link is golang's url rewriting, in order to be compatible with php projects , don’t misunderstand!

PHP Concurrency Test
PHP’s QPS is about 1726/s, the highest is about 2100/s, the CPU peak is 50.1%, which is quite scary

In addition, we also tested batch queries for more primary keys. The processing capacity of golang dropped to 4700/s and php to 1078/s. When ab concurrency was increased to 400, php began to have request failures. situation, after
golang’s concurrency was increased to 2500, I was surprised that its performance was still excellent. If you have any doubts, you can test it yourself

The conclusion drawn from the above test results is: due to multi-core utilization, golang’s” "Multi-threading", as well as the redis connection pool, make Go far ahead in the concurrency comparison with PHP, and the processing power is about 4 times that of PHP

So it is recommended to maintain a large number of requests and encounter bottlenecks Project students can try to use golang to improve!
