To support concurrent requests, you will need to extend the JMS client to spawn multiple threads, or launch multiple JVM instances, each running the application.
为了支持并发请求，您需要扩展JMS客户机，使其产生多个线程，或者启动多个JVM实例，让这些线程或实例各自运行应用。
Because multiple concurrent XML HTTP requests can be scheduled in parallel, our application essentially becomes a concurrent program — and concurrency is hard.
由于可能同时调度多个并发的XMLHTTP请求，应用程序本质上变成了一个并发程序，而并发很难实现。
The classic discussion application database scaled up to 200 concurrent users.
这个经典的讨论应用程序数据库可扩展至 200个并发用户。
In a very simplistic situation where a user-base application is CPU bound, it would be ideal to create a matrix that compares processor allocation to a reasonable number of concurrent users.
在用户应用程序受限于CPU的情况下，建立一个基准比较处理器的分配和合理的并发用户数非常理想。
That means application 1 may use INDEX 1, while application 2 uses INDEX 2, but concurrent use of INDEX 1 in both applications is not allowed.
这意味着，应用程序1可能使用索引 1，同时应用程序2使用索引 2，但是不允许两个应用程序中同时使用索引 1 。
Concurrent deployment of different applications to different application servers or to different application server clusters.
向不同的应用程序服务器或不同的应用程序服务器群集并发部署不同的应用程序。
The application can continue processing and handle more concurrent traffic because resources are not tied up waiting for responses.
应用程序能继续处理更多并发流量，因为资源没有被绑定为等待响应。
Once all the concurrent work is done, or if free memory is exhausted ahead of schedule, the application is halted and the collection is completed.
如果已经完成所有并发工作，或者闲置内存提前耗尽，则将中止应用程序并完成收集工作。
There can be no concurrent users (the application has exclusive access to the database files), but there are no additional threads nor TCP connection overhead.
不能存在并发用户(应用程序独占地访问数据库文件)，但因此也没有额外的线程和TCP连接开销。
Supporting the same number of Concurrent users in these types of application will require larger system capacity.
在这些类型的应用程序中支持相同数量的Concurrent用户将需要更大的系统容量。
In addition to considering the requirements of the average number of Concurrent users, the complexity of your application also influences the resources required.
除了考虑Concurrent用户平均数的需求外，您的应用程序的复杂性也会影响资源需求。
