返回当前正在窃取或执行任务的线程数的估计值。
Returns an estimate of the number of threads that are currently stealing or executing tasks.
r——在所选择的任意采样间隔期间的平均可运行内核线程数。
R — The average number of runnable kernel threads over whatever sampling interval you have chosen.
例如，将多个连接分插或集中到一个线程上，可以减少总线程数。
For example, concentrating or multiplexing multiple connections on a single thread allows for a reduction in the number of overall threads.
第一个变化是将最大线程数从每处理器25个线程增加至250个线程。
The first change is increasing the default maximum number of threads from 25 per processor to 250 pre processor.
在使用JDK 1.6的情况下，JVM可以处理15K到30 K的线程数。
Under JDK 1.6 the JVM can handle between 15k and 30k threads.
测试客户端产生指定的线程数，每个线程都通过它自己的URL对象提供。
The test client spawns the specified number of threads, each supplied with its own URL object.
通过此属性，我们可以设置消息侦听器服务用于运行侦听器端口的最大和最小线程数。
With this property, we can set the maximum and minimum number of threads used by the message listener service to run the listener ports.
返回处于未阻塞状态等待加入任务或其它同步管理的工作线程数的估计值。
Returns an estimate of the number of worker threads that are not blocked waiting to join tasks or for other managed synchronization.
当线程的总数超过web容器的最大线程数时，那么所有新的请求都将被拒绝。
When the total number of threads becomes larger than the maximum threads in the Web container, then all new requests are rejected.
而使用同步则无法达到这种并行程度，因为servlet线程池中的线程数是有限制的。
In the synchronous case, this level of parallelism isn't achievable, because the limiting factor is the number of threads in the servlet thread pool.
图9显示选择的用户/线程数是1；这创建一个数据库mail1.nsf。
The screenshot in figure 9 shows a users/threads selection of 1; this creates one database, mail1.nsf.
但为了在可控的系统中保持线程数，GAE会强迫任何应用程序发起的连接在5到10秒后关闭。
But in an effort to keep the number of threads in the system under control, GAE forces any application-initiated connection to close after 5 to 10 seconds.
对于该模型的一个关键问题是增加工作线程数会加剧对工作队列的争用(如图3所示)。
A key problem with this model is that increasing the number of worker threads increases the contention on the work queue (this is shown in Figure 3).
返回当前正在窃取任务或执行任务的线程数的估计值，此方法可能高估活动线程的数量。
Returns an estimate of the number of threads that are currently stealing or executing tasks. This method may overestimate the number of active threads.
如果服务器是在物理内存上运行，那么您可以看到实时线程数，甚至能够看到服务器的已经运行时间。
You can see if your server is running low on physical memory, the number of live threads, and even how long the server has been up and running.
然而，增加并行CSLD任务的数量，特别是增加它们内部的线程数，并不是件容易的事情。
Increasing the number of parallel CSLD tasks and particularly their internal threads, however, is not as straightforward.
哪些线程阻止?这取决于一些随机因素，例如系统上的负载、等待计划程序的线程数等等。
Which threads resume and which threads block depends on random factors like the load on the system, the number of threads waiting for the scheduler, and so on.
该查询将返回 2005 年6 月20 日下午 1 点 24 分之后所有观察值的线程数。
This query will return the thread count for all observations after June 20th, 2005 at 1:24 PM.
线程数越多，就允许Web容器为Web服务器中的更多当前请求提供服务，从而提高系统的性能。
A high number of threads allows the Web container to serve more concurrent requests from the Web server and hence improves the performance of the system.
该模型扩展了固定优先级调度模型，同时通过实现模型中线程数的减少实现了运行时的低开销。
It expands a fixed priority scheduling model and minimizes run-time costs by minimizing the number of threads in the implementation.
为获得最佳线程数，需要经过一些试验和失败，但一个很好的经验法则是，每100个并发会话分配一个线程。
It takes a bit of trial and error to get the optimal number of threads, but a good rule of thumb is 1 thread for every 100 concurrent sessions.
