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 use epoll, but not sharing the memory. It sounds like it might be a nice option for the future, however.

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 around my problem without changing too many of those already existing design. That's is when the epoll-style idea came out. + epoll-styled design is seems suits better for my application by nature. I really hope Golang can have it built in though.

Consider starting with a simple trial version of your program would get you up and running with less effort. This way you could see whether CPU or memory is the limiting factor, and could work to optimize just that factor (and not waste time on the wrong factor). Or perhaps the trial version will achieve your goals without having to do any optimization.

Thank you for reply. No guys, it's me using too many memories, not Goroutine. However, I believe if I can make those code in epoll-style, I can then build a task queue to handle those connections one by one in a queue when they back to active. For example, start one *accepter* goroutine + few *worker* goroutines. Then I could do buffer sharing within each *worker* instead of each connections. Which well reduce a huge bunch of memory requirement + also reduce numbers of goroutine. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
