Re: [go-nuts] Re: How can I implement a TCP server using a model which similar to epoll (or kqueue, IOCP) rather than just using goroutine for each client?

Hi John, The application is working right now. Current work for me is to found a way to reduce it's memory footprint as it will take at least 1GB memory to hold only C10K idle connections. I know it's mainly me causing such memory usage, so I just want to know if there are a better way to get

Ni Nick. Is 1GB too much? What is your target for number of connections and max memory size? You are using about 100KB per connection? Is there any way to reduce this? The goroutine certainly isn’t much of that. Perhaps some way of using a smaller buffer while idling? Go does us

Re: [go-nuts] How can I implement a TCP server using a model which similar to epoll (or kqueue, IOCP) rather than just using goroutine for each client?

If most of your connections are idle most of the time, and your memory usage comes from something like buf := make([]byte, 65536) n, err := conn.Read(buf) // <-- block here for ever you could simply use a smaller buffer for the read that takes a long time. For example, if the message is length

Re: [go-nuts] Re: How can I implement a TCP server using a model which similar to epoll (or kqueue, IOCP) rather than just using goroutine for each client?

Well, 1 GB memory is certainly too many as they are mostly idle. They *should* cause as little as zero when in idle, right? I really hope they can add that (IO Notify Poll?) into Golang so I can implement my server in other models instead of One-Connection-One-Goroutine one. On Monday, March

Re: [go-nuts] How can I implement a TCP server using a model which similar to epoll (or kqueue, IOCP) rather than just using goroutine for each client?

I don't know. I thought about it before but believe it will create some design complexity in my application. As currently I maybe able to re-implement some kind of polling mechanism from the ground level, I don't think I'll play that large'n'small buffer game. + It's always fun to play with the

Your example function is named ExampleMain(). This means that it is supposed to document function Main() or type Main. However, there is no function Main() or type Main in the package. Thus the example is not visible in the documentation because there is nothing for it to attach to. See for examp
