步骤1.1：检查查询执行时间。
执行时间：在执行规则时发生了什么？
这些规则可以显著减少查询执行时间。
但是，这是否会影响查询的执行时间？
But does this have an impact on the query's execution time, too?
因此，执行时间上的差距并不是很明显。
Therefore, the differences regarding the execution time seem to be irrelevant.
磁盘I/O 的减少也减少了执行时间。
所以，执行时间随资产数量的三次方增长。
So, the execution time grows cubically as a function of the number of assets.
由于已经预先编译好，所以减少了执行时间。
异步的最终目的是减少联邦查询的执行时间。
The ultimate aim of asynchrony is to reduce the execution time of the federated query.
你应该能够看到平均执行时间和每秒事务数。
You should be able to see the mean execution time and transactions per second graphs by hitting this servlet.
一个SQL语句的执行时间为4毫秒。
指定了较高优先级的线程拥有较长的执行时间量。
Threads with higher assigned priorities are given longer time quanta to execute.
这些测试有一点难于编写，执行时间也要长得多。
These tests are a bit more difficult to code and take considerably more time to execute.
执行时间的标准偏差估值点是645.586微秒。
A point estimate for the standard deviation of the execution time is 645.586 microseconds.
在针对大数据集执行时，这会很明显地影响执行时间。
This may significantly impact the execution time of the rule when executed on a large data set.
视图显示应用程序执行时间的统计结果(见图22)。
The execution statistics view displays statistics about the application execution time (Figure 22).
说明：SQL查询一般执行时间很稍长一些。
这个更详细的执行时间视图开始展示一些有用的细节了。
This more detailed view of the execution time is starting to show some good details.
如预期一样，同步复制的代价使事务执行时间明显延长。
As expected, the cost of replication adds significantly to the execution time of a transaction.
可预测性：线程优先级监管执行的次数，执行时间一致。
Predictability: Thread priorities govern the order of execution, and execution times are consistent.
通过检查日志语句的执行时间来查明存储过程的性能问题。
To pinpoint performance problems in the stored procedures by examining execution times of the logging statements.
queryModule：度量ogql查询的执行时间。
QueryModule: Measures the execution time of your OGQL queries.
一种看似聪明的方法是不断度量执行时间，直到结果值收敛。
You could try the seemingly clever approach of measuring execution times until they converge.
哪些SQL语句消耗的CPU、排序和执行时间最多？
What SQL statements are consuming the most CPU, sort, and execution times?
清单7中的代码在我的配置上的执行时间是总是4.91秒。
I consistently find that the code in Listing 7 executes in 4.91 seconds on my configuration.
执行时间超过给定时间范围的查询就称为慢速查询。
Queries that take more than a given amount of time to execute are called slow queries.
其持续时间没有考虑重试延迟，因为这没有包含在执行时间中。
The duration does not take into account the retry delay, since this is not part of the execution time.
好的接口设计可以大大减少远程调用的数量，从而节省执行时间。
A well-designed interface can greatly reduce the number of remote calls and thus execution time.
确保调度程序将该生命周期任务安排为具有30秒钟的执行时间。
Make sure to schedule a life cycle task with the scheduler with a fire time of 30 seconds.
比如，用来在事务中封装某个方法调用，或者记录方法的执行时间。
Used, for example, to wrap a method call in a transaction, or time the execution of a method.
