Java socket setSoTimeout和性能命中

Question

我想优雅地关闭serversocket。到目前为止我已经有了这段代码：

    @Override
    public void init() throws IOException {


        listener = new ServerSocket();
        listener.setSoTimeout(1);
        listener.setReuseAddress(true);
        listener.bind(new InetSocketAddress(85));
        clientProcessingPool = Executors.newFixedThreadPool(50);

        while (!clientProcessingPool.isShutdown()) {
            try {
                Socket socket = listener.accept();
                clientProcessingPool.submit(new StlExecutor(socket, this));
            } catch (SocketTimeoutException e) {

            } catch (Exception e) {
                logger.error("", e);
                e.printStackTrace();
            }
        }
        listener.close();
    }


    public void stop() throws Exception {
        clientProcessingPool.shutdownNow();
    }

设置如此低的SO_TIMEOUT是否合理？什么是合理的价值呢？什么是性能影响？
