还有一种可能是在启动时派生一个单独的低优先级的线程，当系统空闲时再去完成初始化，不过这种方法需要特别注意处理好同步。
Another possibility is to fork a separate low-priority thread during startup to perform initialization when the system is idle, although this choice requires more care to handle synchronization.
为了获得最可靠的结果，在你运行这个命令时，系统应该是空闲的。
For the most reliable results, the system should be idle when you run this command.
仅当您知道存在足够的空闲系统资源时才调整线程的数量。
Only adjust the number of threads if you know that there are enough spare system resources.
注意：在执行这些测试时，测试系统是空闲的，测试时没有运行其他任何活动。
Note: Our test system was idle, with no other activity running, when we ran these tests.
文件系统统计信息用来提供加密、临时、内部文件系统的空闲和总的空间信息。
File system statistics are provided for free and total space of the encrypted, temporary, and internal file systems.
该命令显示系统中的空闲内存、已使用的物理内存和交换内存的总量，以及内核所使用的缓冲区。
The command displays the total amount of free, used physical, and swap memory in the system, as well as the buffers used by the kernel.
系统资源不被不执行任何工作的连接(空闲连接)所占有。
System resources are not held up by connections that perform no work (idle connections).
共享内存是从系统的空闲内存池中分配的，希望访问它的每个进程连接它。
Instead, Shared memory is allocated from the system's free memory pool and is annexed by each process that wants access.
最重要的更改是处理分页问题，即使系统拥有足够的空闲内存，数据库服务器频繁地交换出计算性页面也可能导致这个问题。
The most important changes were made to address paging issues, where database servers frequently page out computational pages, even though the system has enough free memory.
这些状态帮助空闲中的系统节省电能。
These states can provide power savings when the system is idle.
如果装载了该应用程序的系统异常繁忙，那么利用网格计算，应用程序可以在格网中空闲的或未充分利用的系统上运行。
With grid computing, if the system housing the application is unusually busy, the application may run on an idle or underutilized system that is part of the grid.
开始使用EVMS的最佳方法是找一个空闲的硬盘，并将其安装到系统上。
The best way to start playing with EVMS is to find a spare hard drive and install it in your system.
这取决于没有会话关联的请求到达系统中的速度，以及热服务中的空闲 TCB 的数量。
This depends on the rate at which requests that do not have session affinity arrive into the system and the number of free TCBs in the hot servant.
大多数UNIX系统会尝试用空闲内存执行缓存，这就是系统常常看起来没有空闲内存的原因。
Most UNIX systems try to use free memory for caching, which is why it often looks like your system has no free memory.
同样，终结通常是后台任务，所以它们常常在系统的空闲时间执行。
Likewise, finalizers are normally processed as a background task, so their cost is usually amortized across the system's idle time.
这通常会释放文件系统中的空间，但由于内部快照很小，所以文件系统中的空闲空间变化也很小。
This would normally free up space in the file system but because of the internal snapshot there is very little change in the amount of free space in the file system.
它是处理磁盘上的文件系统的基础，因为它定义文件系统的管理参数(例如，块的总数、空闲块和根索引节点)。
It provides the basis for dealing with the on-disk file system, as it defines the file system's managing parameters (for example, total number of blocks, free blocks, root index node).
它还列出了各个逻辑分区的使用率统计信息，包括在不同模式(用户、系统、空闲和等待)中有权使用的容量百分比。
It also lists utilization statistics of each logical partition, which includes percentage of entitled capacity in different modes (user, system, idle, and wait).
使用df，您可以确定整个文件系统的空闲空间和空间使用情况，但这只是描述了部分信息。
You can determine the free space and usage for entire file systems using df, but this only gives you part of the picture.
其中关键的一行是提取每个文件系统中空闲磁盘空间的大小。
The key is the line that extracts the amount of free disk space for each file system.
因此，将maxperm作为严格限制的缺点是，非计算性分页的数目不能超出maxperm的限制，并且在系统中具有空闲内存的时候，也不能使用更多的内存。
Thus, the disadvantage with making maxperm a strict limit is that the number of non-computational pages cannot grow beyond maxperm and consume more memory when there is free memory on the system.
先来看看CPU统计信息，这些列分别显示了用户(us)、系统(sy)和空闲(id)百分比。
Dealing with the CPU statistics first, the columns show user (us), system (sy), and idle (id) percentages.
free命令显示系统的空闲内存和已用内存。
The free command displays the amount of free and used memory in your system.
您可以使用tunefs工具或在创建文件系统时，调整保留的空闲空间的大小。
You can adjust the amount of free space that is reserved (using the tunefs tool), or when creating the file system.
操作系统对CM服务器的推荐空闲硬盘空间指定如下。
Recommended free disk space with CM Server is as follows for the operating systems specified.
