Execute task enough times to ensure that its steady-state execution profile has emerged.
执行task足够多次,以确保出现稳定状态的执行数据。
Figure 3 shows the general trend in start-up performance and steady-state performance.
图3展示了启动性能和稳定状态性能的总体趋势。
So far, we've looked only at the application's steady-state aspects — that is, how it will work once it's running.
至此,我们只观察了应用程序的稳定方面——也就是说,它开始运行之后的工作方式。
In our next test, we started up 2000 users over a period of 80 minutes, followed by a steady-state period of 90 minutes.
在下一个测试中,我们在80分钟的时间段内启动2000个用户,接下来是一个90分钟的稳定状态。
Assuming that you want to measure this steady-state performance, you need to understand all the factors that lead up to it.
假设希望度量稳定状态下的性能,就需要了解影响这个过程的所有因素。
What this means for benchmarking is that a task might need to execute many times before its steady-state execution profile emerges.
这对基准测试的影响在于,任务可能需要执行许多次,才能达到稳定状态。
The test plan can be configured to produce a steady-state workload or to introduce variability by alternating the load between multiple virtual machine groups.
配置测试计划来产生状态稳定的工作负载,或者通过调整多个虚拟机组之间的负载来产生变化。
This might be acceptable during short periods of heavy activity, but it should not be relied on for the steady-state operation of the server and its applications.
这在短期的大量活动时还可以接受,但要获得服务器及其应用程序的稳定操作状态,则不应依赖于此解决方案。
You can then use a value from this range as the initial size of the heap, which will prevent the initial delays associated with growing the heap to the steady-state value.
然后,可以使用这个范围内的某个值作为堆的初始大小,这会消除堆增长到稳定状态导致的初始延迟。
So, even if you followed the advice in the preceding section and appear to have achieved steady-state performance, you need to be aware that performance could abruptly change.
因此,即使按照前一节中的建议实现了稳定状态,也要注意性能仍然可能突然下降。
In particular, if you think that you have achieved steady-state performance and start benchmarking, but then find that compilation occurred inside your benchmark, then you can abort and retry.
尤其是,如果您认为已经到了稳定状态并开始基准测试,但是随后发现在基准测试期间发生了编译,那么可以中止并重试。
It corresponds identically to the leftover glow predicted by the Big Bang, and contradicts the predictions of Steady-State theory.
它符合大爆炸理论预测的剩余辐射,而与稳态理论的预测相反。
Back then, there were two major rival theories about the origin of the Universe: the Big Bang theory and the Steady-State model of the Universe.
当时,对宇宙的起源有两个主要的对立理论:宇宙大爆炸理论,稳态宇宙模型。
By contrast, the Steady-State model said that the only light that should be around is starlight, either coming directly from stars or reflected off of the gas throughout the Universe.
与此相反,稳态模型说,整个宇宙中唯一的辐射应该是星光,无论它是直接来自恒星或反射自气体。
什么是稳定状态?
For most of the time, we live in a very steady state.
大多数时候,我们生活在一个非常稳定的状态。
You can use the steady state as the time range for your report.
您可以使用稳定状态作为报告的时间范围。
They have kind of maintained themselves in a steady state.
它们似乎保持了平稳的状态。
The red arrow indicates the point where steady state is considered to be reached.
红色箭头表示被视为达到稳定状态的点。
In production, you must plan to have enough capacity for your peak loads, not the average steady state.
在生产负载中,必须计划好有足够的容量来应付尖峰负载,而不是平均的稳定状态。
If activity of any system component is increasing throughout the test run, the system has not reached steady state.
如果任何系统组件的活动在测试运行过程中增加,则系统不会达到稳定状态。
Figure 4 shows the filtered painting in its final, steady state.
图4显示了过滤图画的最终稳定状态。
The red arrow indicates the point where a steady state is considered to be reached.
红箭头表示被视为达到稳定状态的点。
Run the performance workload to create a heavy workload on the system under test until it reaches steady state.
运行性能工作负载,在被测系统上创建工作负载直到它达到稳定状态。
The graphs below show servers running a Server.Load workload overnight that has reached steady state.
下图显示了整晚运行Server.Load工作负载的服务器已经达到稳定状态。
In general, the initial performance is usually relatively slow, and then it greatly improves for a while (usually in discrete leaps) until it reaches a steady state.
一般来说,最初的性能往往相当低,然后性能显著提高(常常出现几次性能跃升),直到到达稳定状态。
For the first time in 70,000 years, for lots of reasons, human numbers will have reached a steady state.
这是七万年以来人口数字第一次,由于各种各样的原因达到一个稳定的状态。
The other option is to iteratively increase the cache size and run the application under peak steady state load until the PMI metrics report no more cache discards.
其一种方法是迭代式的增加缓存大小并在峰值稳定状态负载下运行应用程序,直到PMI指标不再报告任何缓存丢弃操作。
If this metric does not reach a steady state value and continues to decrease over time, then you have a clear indication that a memory leak is present within the application.
如果此指标未达到稳定状态值,并随时间持续减小,则明确表示应用程序中出现了内存泄漏。
