NopCommerce의 Autofac 부하(CPU, Memory)

정확한 원인 분석은 아니지만, 하나의 현상이라고 기록해 둘 만한 것 같습니다.

언제부터인지는 모르겠지만 근래 NopCommerce는,

Open-source & FREE e-commerce solution: NopCommerce
; http://www.nopcommerce.com/

내부적으로 DI Container로 Autofac을 사용하고 있습니다.

Autofac - is an addictive Inversion of Control container for .NET Core, ASP.NET Core, .NET 4.5.1+, Universal Windows apps, and more.
; https://autofac.org/

그런데, 지인이 테스트하는 서버에서 CPU 사용량이 너무 높다면서 문의를 해왔습니다. 환경은, x64 .NET 4.0이었고 단지 테스트 서버이다 보니 메모리가 4GB로 낮았습니다. 2개의 테스트용 NopCommerce 사이트를 구동하면 각각 2GB 이상의 private 메모리를 차지하면서 CPU 100% 현상이 발생했습니다.

이때의 스레드 상황을 Process Explorer로 보면 다음과 같습니다.

"clr.dll!InstallCustomModule" 항목이 눈에 띄는데요. 이런 항목이 있는 스레드 2개를 살펴보니 하나같이 "Autofac.dll"의 콜 스택이 보였습니다.

이걸 보니, Ninject DI 프레임워크의 성능 분석 사례가 떠오르더군요. ^^

Autofac을 어떻게 적용했는지는 구체적으로 살펴보지는 않았지만, 암튼 nopCommerce 측의 적용에 문제가 있는 것이 아닌가 생각됩니다.

[ryujh] 안녕하세요.

내용 중에 '내부적으로 DI Container로 Autofac을 사용하고 있습니다' 이렇다면 NopCommerce 에 포함되었다는 것인데
NopCommerce 에서 Autofac 을 분리 가능한지 문의합니다. 소스 수정이 필요하다면 DI Container 를 사용하기 위해 소스 수정 작업이 더해지는 결과인데 DI 의 이점이 충분히 큰지요?

DI 사용해본 적없고 소스 수정 작업만 걱정하다보니 이런 질문하는군요. 감사합니다.

글쎄요. 그 질문은 NopCommerce 측에 하시는 것이 더 좋지 않을까요? ^^
