client socket time out

[whutjs]

Hi， jjenkov， I really appreciate you blog because I've learned how to use Java NIO.And I have written a Http server based on your code.It works well when there are not much connections.But when I test it with high concurrent connection(10K connection), almost all the connections are time out(Socket time out). I just don't know how to optimize it now. Could you give me some advice? Thanks anyway!

Hi,

I cannot help you with that just yet. I will need to look into all that
myself (with another protocol than HTTP) next month.
Maybe I can get back to you by then. I know it's a long time to wait, but
hey, at least I am getting to it.

Oh, and if you find a solution before then, please let me know!

I'm still studying the sources, but I have a guess: When HttpMessageReader.read() calls Message.writeToMessage(), and there is no space for the new content, and no free block to expand, then the content of the ByteBuffer will be lost. (just a guess, didn't tried)
