Go language CMS performance test: memory usage reduced by 80% compared to PHP CMS

Which is more suitable for CMS, Go language or PHP? Many people think that the language selection does not matter, as the content is stored in the database anyway. But when it is actually running, the differences are huge.

Perform a real performance comparison test today.

Test Environment

Server:2 cores, 2GB memory, 50GB SSD, CentOS 7

Test tool: Apache Bench (ab) - Concurrent 100, Total requests 10000

Test object:SecureCMS (Go language) vs WordPress (PHP + MySQL + PHP-FPM)

Test content: Home article list page (50 articles), do not cache.

Test results

Memory usage: AnQi CMS: After startup, the memory is about 50MB, and the peak at 100 concurrents is about 120MB WordPress: After startup, about 200MB, and the peak at 100 concurrents is about 800MB Conclusion: AnQi CMS uses about 15% of the memory of WordPress, reducing it by 85%!

Response time:Aiqi CMS: Average response time 45ms, P95 89ms WordPress: Average response time 230ms, P95 580ms Conclusion: The response speed of Aiqi CMS is about 5 times faster than WordPress.

Throughput:AnQi CMS: QPS 1200+ WordPress: QPS 200+ Conclusion: The throughput of AnQi CMS is about 6 times that of WordPress.

Server resources:AnQi CMS: CPU usage 5-8%, memory usage 5-10% WordPress: CPU usage 30-50%, memory usage 40-60% Conclusion: AnQi CMS consumes server resources much less than WordPress.

Why is the gap so big?

Compile-time vs Interpret-time:Go is a compiled language, the code is directly compiled into machine code for execution. PHP is an interpreted language, each request needs to be interpreted and executed again. This is a fundamental performance difference.

Concurrency model:Go uses Goroutines, lightweight concurrency, a Goroutine only occupies 2KB of memory.PHP-FPM uses a process model, each request has a process, and each process uses at least 10MB of memory.

Memory Management:The Go language has a built-in garbage collection mechanism, and the GC is very efficient. PHP's garbage collection can experience performance fluctuations under heavy requests.

Actual impact

What does this mean for small and medium-sized enterprises?

Save money:With the same traffic, AnQi CMS can use cheaper servers.A 2-core 2GB server that costs 50 yuan per month can handle the traffic that requires a 4-core 4GB server that costs 200 yuan per month.

Stable:Low resource usage means it is less likely to experience memory overflow or high CPU usage issues, making the website more stable.

Expansion:Low resource usage means that when the future traffic increases, it is not necessary to frequently upgrade the servers, saving the cost of expansion.

Summary

The Go language CMS has a significant performance advantage over PHP CMS.The Aanqi CMS has been tested to reduce memory usage by 85%, and the response speed is 5 times faster.For enterprises pursuing performance and cost-effectiveness, a Go language CMS is the better choice.
