可以尝试在代码中使用更高效的算法或优化，以降低延迟。另外，也可以对系统进行优化，如增加CPU核心数量、使用更快的硬件等。以下是一个使用Java编写的Aeron Ping-Pong测试的示例代码：

import io.aeron.Aeron;
import io.aeron.driver.MediaDriver;
import io.aeron.logbuffer.Header;
import org.agrona.concurrent.BusySpinIdleStrategy;
import org.agrona.concurrent.IdleStrategy;

import java.nio.ByteBuffer;

public class PingPong {
    private static final int PONG_STREAM_ID = 21;
    private static final int PONG_CHANNEL = "aeron:udp?endpoint=localhost:40124".hashCode();
    private static final int PING_STREAM_ID = 20;
    private static final int PING_CHANNEL = "aeron:udp?endpoint=localhost:40123".hashCode();
    private static final int MESSAGE_LENGTH = 192;

    private static final byte[] PONG_BUFFER = new byte[MESSAGE_LENGTH];
    private static final ByteBuffer PONG_BYTE_BUFFER = ByteBuffer.wrap(PONG_BUFFER);

    public static void main(final String[] args) {
        try (final MediaDriver driver = MediaDriver.launchEmbedded();
             final Aeron aeron = Aeron.connect();
             final Subscription subscription = aeron.addSubscription(PING_CHANNEL, PING_STREAM_ID);
             final Publication publication = aeron.addPublication(PONG_CHANNEL, PONG_STREAM_ID)) {

            while (!subscription.isConnected() || !publication.isConnected()) {
                Thread.sleep(1);
            }

            final IdleStrategy idleStrategy = new BusySpinIdleStrategy();
            final FragmentHandler fragmentHandler = (buffer, offset, length, header) -> {
                PONG_BYTE_BUFFER.clear();
                PONG_BYTE_BUFFER.put(buffer, offset, MESSAGE_LENGTH);
                publication.offer(PONG_BYTE_BUFFER, 0, MESSAGE_LENGTH);
            };

            while (true) {
                idleStrategy.idle(subscription.poll(fragmentHandler, 1));
            }
        }
        catch (final Exception e) {
            e.printStackTrace();
        }
    }
}

该示例代码演示了如何使用Aeron进行Ping-Pong测试，并且尽量减少延迟。在此示例中，我们使用了忙旋转空闲策略（BusySpinIdleStrategy）将线程阻塞，以确保处理速度最大化。由于消息的长度为192字节，因此我们使用了一个ByteBuffer来缓存发送和接收的消息。如果您发现延
