HI there. I'm working on spring-boot-kotlin and trying to replace apache-http/okhttp to CIO. Can I get a performance comparison?

CIO is probably slower, just less optimized But if you really want to get real comparison, you should measure it for your usecase, not some generic benchmark

If you are using Spring then also take a look at their Webclient

I just wanna coroutine base client cause less resources than thread. I'm managing like gateway server using many http request and that is not special it just simple get/post call.

But Spring WebClient already non blocking and can be easily used with coroutines, so i doubt that you

What are the benefits using webclient? CIO is very simple via ktor-client-engine. ah.. I'm using Ktor-client(apache-http/okhttp engine).

Well, if you already use spring boot, webclient looks as a native solution, doesn’t require bringing additional dependencies like ktor

ok. I will try. thanks

just use webclient It also has a suspended method call awaitBody
