Java AWS SQS Batch SendMessageBatchRequest速度非常慢

我的应用程序使用SendMessageBatchRequest向AWS-SQS发送每个请求10条消息。每条消息的大小小于250字节。该应用程序预计每天发布大约一百万条记录。但是信息被发布的速度要达到这一点非常慢

AmazonSQS sqs = null;
sqs = new AmazonSQSClient(new BasicAWSCredentials("accessKey", "SecretKey"));
//the below entries are added via a for loop picking the messages from a queue
//the typical queue size will be 20k messages
//AmazonSQSClient is created once and is used until the code comes out of the for loop

List<SendMessageBatchRequestEntry> entries = new ArrayList<SendMessageBatchRequestEntry>();
entries.add(new SendMessageBatchRequestEntry(messageBatchRequestId, "250kbJSONString"));
 //Once the batch count reaches 10,the following code is called 

CreateQueueRequest createQueueRequest = new CreateQueueRequest("CLIENT-TEST");
String myQueueUrl = sqs.createQueue(createQueueRequest).getQueueUrl();

SendMessageBatchRequest sendMessageBatchRequest = new    SendMessageBatchRequest(myQueueUrl);

sendMessageBatchRequest.setEntries(entries);
long timeBeforePost = System.currentTimeMillis();
SendMessageBatchResult smbResult = sqs.sendMessageBatch(sendMessageBatchRequest);
long afterPost = System.currentTimeMillis();
log.trace("time taken %s ",(afterPost-timeBeforePost));

有些帖子需要7秒、16秒等时间才能返回，这正常吗？我有一些帖子需要300秒才能从方法调用返回。我是否遗漏了什么，我的应用程序目前是单线程的，我计划使它成为多线程的，以并行方式处理消息，但同样，有些消息需要几秒钟，有些消息需要几十秒/数百秒，这是严重错误的。请帮忙

非常感谢，我的第一个猜测是您的本地计算机和SQS之间存在延迟问题，SQS处理传入消息的速度肯定比您看到的数字快得多

也许最好的办法是将一个EC2实例启动几个小时，大小与您的本地计算机相似，并进行相同的测试以查看问题是否消失。

考虑创建一个AmazonSQS客户端，并对每个请求重复使用它。客户机提供连接池并保持连接打开以优化重用。它也可能在查找区域以查找要连接的端点。最好在整个应用程序中重用aws客户端，而不是针对每个请求

SDK中的服务客户端是线程安全的，为了获得最佳性能，您应该将它们视为长寿命对象。每个客户端都有自己的连接池资源，当客户端被垃圾收集时，连接池资源将关闭

在哪里进行发布？是EC2实例还是本地的？如果是EC2，您的实例有多大？它不是EC2。本地机器：型号名称：英特尔（R）至强（R）CPU E5320@1.86GHz 16G内存。该应用程序正在apache Tomcat实例上运行，内存为2G
