A Performance Session is a collection of Settings that you configure to determine how an application is profiled.
性能会话是一个设置集合，可对该设置集合进行配置，以确定应用程序的分析方式。
To obtain the data that you want to analyze, you must first create a performance session and then run the session.
若要获取需要分析的数据，必须先创建性能会话，然后运行该会话。
To profile one or more DLLs in an application, you create a performance session that includes the. DLL files as targets.
要分析应用程序中的一个或多个dll，请创建将.dll文件作为目标包括的性能会话。
This event is not portable, but still available to the developer for a specific performance session on a specific platform.
这个事件无法移植，但是开发人员仍然可以在特定平台上的特定效能工作阶段使用此事件。
Profile an application without the wizard: Learn to use the performance session property pages to create a performance session.
不使用精灵剖析应用程式：了解如何使用效能工作阶段属性页来建立效能工作阶段。
If you want to count a particular event when you use the profiler, for example, L2 cache misses, you can build a performance session around that event sender.
如果您在使用探查器时要对特定事件进行计数(例如l2缓存未命中数)，则可以围绕该事件发送方生成性能会话。
In addition, the Performance Session generates and stores reports on various aspects of running code, such as functions calls, memory allocations, and time that is spent running functions.
此外，性能会话还能生成并存储有关运行代码各方面内容的报告，如函数调用、内存分配以及运行各个函数所用的时间。
Storing the object on the session is not necessary, but in most cases will improve performance.
可以不将对象存储到会话中，但在大多数情况下，这样做将提高性能。
So by now, we have hopefully convinced you that using a real cache API for cache data, instead of the session, is something that gives you real benefits in performance and scalability.
因此，到目前为止，我们希望已说服您将真正的缓存API用于缓存数据，而不是使用会话，它将向您提供性能和可伸缩性方面的真正好处。
This causes degraded performance as increasing amounts of time and bandwidth are absorbed in maintaining consistency of session backups across the cluster rather than processing user requests.
这会造成性能的下降：越来越多的时间和带宽花在了在集群中维护会话备份的一致性，而不是用来处理用户请求。
J2EE applications typically store this kind of data in in-memory session objects for better performance and for a better user experience.
J2EE应用程序通常将此类信息存储在内存中的会话对象中，以实现更好的性能或实现更好的用户体验。
However, the resulting performance can be worse with a multi-row schema, since gathering attributes out of the session might cause multiple queries.
不过，多行模式的性能可能相对较差，因为从会话收集属性可能会导致进行多次查询。
The larger the session state, the more your scalability and performance suffers.
会话状态越庞大，对可伸缩性和执行能力的影响越大。
For example, if the database can only process 10 messages at time, increasing the JMS listener Max session from 20 to 30 will not improve performance.
例如，如果数据库一次只能处理10条消息，那么将JMS监听器最大会话数量从20增加到30将不能提高性能。
At its fourth session, the COP reviewed the performance of the current and previous workplans and adopted the workplan and the budget for the biennium 2012–2013.
缔约方会议第四届会议回顾了当前和以前工作计划的执行情况，并通过了2012-2013双年度工作计划和预算。
In addition, session synchronization adds overhead, which impacts server performance.
此外，会话同步增加了开销，从而影响服务器性能。
The mechanisms can be used to make the session state available, but there is a performance cost in using them.
此类机制可以用于提供会话状态，但使用它们会有性能损失。
The overhead of a local session EJB is relatively low, so performance should not be an issue, even if they are stateful.
本地会话ejb的开销很低，所以即使他们是有状态的，性能不是问题。
Both of these perform basic Web session functions, such as recording and playback, but lack many of the useful features available in commercial products, such as Rational Performance Tester.
这两个都执行基本的Web会话功能，例如记录和回放，但是缺少许多商业产品，例如，RationalPerformance Tester，中的有用特性。
You may see a Session startup dialog that discusses startup performance (Figure 15).
您可以看到一个讨论启动性能的SessionStartup对话框(图15)。
For performance optimization, a local interface can be added to the session facade.
为了性能的优化，可以将一个本地接口添加到会话Facade。
Whatever mechanism you decide on for session replication, you can improve the performance and scalability of your Web application in a few ways.
不管决定使用什么机制进行会话复制，可以用几种方式改进Web应用程序的性能和伸缩性。
Because session creation is costly, in terms of performance, it is a good strategy to reuse the session object whenever possible.
就性能而言，因为会话创建是昂贵的，所以在可能的时候，复用会话的对象是很好的策略。
The controlled transfer of messages, representing workload throttling, can be monitored from the Tivoli Performance Viewer session that we configured earlier.
受控制的消息传递，即可以进行工作负载调节，可以从前面配置的TivoliPerformanceViewer会话中进行监控。
When session beans access the database directly, the overall performance of the system will improve.
当会话bean直接访问数据库时，会提高系统的整体性能。
The network TAB displays performance details about the network connectivity, IO, and so on for the selected session.
Network选项卡显示所选会话的网络连接、IO等方面的性能信息。
From a performance standpoint, servlets and stateless session beans are fairly competitive technologies.
从性能的角度看，servlet和无状态会话bean是相当具有竞争力的技术。
