你可以增加吞吐量以至于加速整个系统，如果你在恰当的时间点让系统的某一个处理做恰当时间的延迟。
You can increase the throughput — speed up the whole system — if you delay single processes within the system at the right time, for the right amount of time.
如果系统中存在正在排队等候的任务，那么系统的响应时间可能会受到排队时间的控制，而不是垃圾收集停顿时间。
In any system where work is queuing up, the response time of the system is likely to be dominated by the queueing time, rather than any garbage collection pauses.
响应时间分解为您显示了系统的每一个部分在测试期间的时间所占用系统运行总时间的比重。

时间管理系统方法之所以不起作用的原因是这些方法是用来管理时钟时间的。
The reason time-management gadgets and systems don't work is that these systems are designed to manage clock time.
确实，有些系统在一天中关机的时间也许要比开机的时间还长。
Indeed, some systems might be turned off for more minutes per day than they're turned on.
但是正如您从中可以看出的，输出的布局在默认情况下不是很理想，它丢失了时间戳，而我认为时间戳正是任何日志记录系统的至关重要的元素。
But as you can see, layout isn't that nice by default; in addition, it's missing a timestamp, which I believe to be a vital element of any logging system.
该策略定义了从系统中删除文件的规则，可根据访问时间、修改时间、文件名、路径、所有者等文件属性对系统中的文件进行删除。
This policy defines the rule to delete the files from the system depending on various file attributes like access time, modified time, file name, path, owner, and so on.
将数据库从主系统移动到辅助系统的方法因情况而异，但是这个过程总会产生一个时间窗，在这个时间窗内，数据还没有完成从一个系统到另一个系统的迁移。
The method of moving database changes from the primary to the secondary system varies, but the process produces a window of time during which data has not migrated from one system to the other.
现实往往是这样的：团队经常会强迫项目小组在规定时间交付系统，这需要构架师正确的评估到这个时间。
The reality is that there are many forces at work in organizations that lie beyond the project team delivering the system, and these need to be accounted for.
了解您的系统将多少时间花费在垃圾收集上，这是很有必要的，但是将过多的时间花费在垃圾收集上将会对系统的性能产生怎样的影响呢？
Knowing how much time your system spends in GC is all well and good, but how does more time spent doing garbage collection actually affect the performance of your system?
当机会和威胁在不可预测的时间出现时，事件驱动的系统必须在外部确定的时间响应事件。
As opportunities and threats appear at unpredictable times, event-driven systems must respond to events at times that are externally determined.
响应时间分解会显示出被测系统的每个部分花费了多少时间。
Response time breakdown shows how much time was spent in each part of the system under test.
短暂的确定性响应时间是指嵌入式系统可以确定它对外部事件作出响应的时间。
Short deterministic response latencies mean that the embedded system can determine the time it will take to respond to an external event.
默认时间，即从运行代码的机器的系统时钟检索到的时间，在大部分情况下被使用。
The default time, which is retrieved from the system clock of the machine the code is running on, is used most of the time.
还可以使用- D开关显示每个系统调用的时间差，时间差表示自前一个事件以来流逝的秒数。
You can also use the -d switch to display each system call with a time delta, representing the elapsed time in seconds since the last event.
当这个系统运行时，响应时间细分数据为您显示了被测试系统的每一部分所花费的时间。
Response time breakdown shows you how much time was spent in each part of the system under test code as the system was exercised.
DB 2跟踪两种不同类型的时态数据：系统时间和业务时间。
DB2 tracks two different types of temporal data: system time and business time.
这些任务包括轮转日志文件以避免装满文件系统、备份数据和连接时间服务器来执行系统时间同步。
