Hi,
I am experiencing slowness connecting to a Java NIO server running in my
Android app.
The server code is fairly boilerplate:
- Create a listening server socket like this:
ServerSocketChannel channel = ServerSocketChannel.open();
channel.configureBlocking(false);
ServerSocket socket = channel.socket();
socket.setReuseAddress(true);
socket.bind(isa);
- Register it with a selector
mMainSelector = Selector.open();
mMainAcceptKey = mServerChannel.register(mMainSelector,
SelectionKey.OP_ACCEPT);
- Enter a processing loop
while (mMainSelector.select(SELECTOR_TIMEOUT) {
.... stuff getting the selected keys ....
SocketChannel socketChannel = channel.accept();
Problem is, it takes about 1-3 seconds from the time the client begins
to connect to when the above code gets to the last line (channel.accept()).
For read/write operations, the select() call returns immediately, which
is expected.
Has anyone else seen this slowness in select() when accepting new
connections?
