一些平台支持建立一大块相邻的内存区,以便能够使用比默认内存分页大小更大的内存分页。
Several platforms provide the ability to establish a large contiguous section of memory using memory pages that are larger than the default memory page size.
那么如何维护分页空间的大小呢?
一般情况下,分页空间的大小应该是真实空间的一到两倍。
Generally, paging space should be one to two times real memory in size.
尽管缓存可能在一定程度上减轻这种性能影响,但如果使用特定大小的数据块检索数据来支持用户界面分页,则可能出现另一个问题。
Although caching might alleviate this to some degree, another problem might arise if data is retrieved in blocks of a certain size to support user interface pagination.
其中说明了,分页空间的推荐初始设置为ram大小的一半加上4gb,但是上限为32gb。
It states that the recommended initial setting for paging space be half the size of RAM plus 4gb with an upper limit of 32gb.
它创建的分页设备的大小等于共享内存池的最大内存值。
It creates a paging device of equal size to that of the maximum memory value of the Shared memory pool.
一个最佳实践是,请记住保持分页空间的大小相同。
One best practice to keep in mind is to keep your paging Spaces at the same size.
SIZE —为此进程(文本和数据)分配的分页空间的实际大小。
SIZE—The actual amount of paging space allocated for this process (text and data).
一个分页就是一个固定大小的数据块。
一个系统可以定义多个分页空间,但是分页空间的大小最好相同,而且每个磁盘上只有一个分页空间。
A system may have more than one paging space defined, but it is best to keep paging Spaces at equal sizes and to limit one paging space per disk.
当系统内存不足以支持所选择的堆大小和系统中正在运行的其他进程时,将出现分页情况。
Paging can occur when there is insufficient system memory to support the chosen heap size along with the other processes running on the system.
分页是为了使页面大小适合设备缓冲可接受的限制而将单个页面分解成多个页面的过程。
Pagination is the process of breaking a single page into multiple pages in order to fit the page size within acceptable limits of the device buffer.
我通常使用几个来自SAN的自定义大小的逻辑单元号(LUN)添加额外的分页空间。
I normally add a couple of custom-sized logical unit Numbers (LUNs) from the SAN for the additional page Spaces.
如果缓冲池大小过大,那么内存使用会超过可用的物理内存,从而导致操作花费更多时间对内存进行分页。
If you set the buffer pool size too high, then system memory usage will exceed the available physical memory, causing the operating system to spend more time paging the memory.
然后列出进程使用的所有dll及其大小,后面是工作集和分页文件使用的统计信息。
It then lists all of the DLLs in use by the process, with their sizes, followed by a summary of statistics about the working set and page-file usage.
比较合理的规则是,把分页空间配置为RAM大小的一半加上4gb,上限为32gb。
A more sensible rule is to configure the paging space to be half the size of RAM plus 4gb with an upper limit of 32gb.
如果工作集略微大于池大小,那么在Hypervisor跨lpar重新平衡内存使用量时,会发生一些分页操作。
If the working sets become slightly larger than the pool size, then some paging will occur as the Hypervisor rebalances the memory usage across the LPARs.
内存影响Notes客户机并发连接(会话)的最大数量、缓存大小和服务器插件任务性能(由于磁盘分页较少)。
Memory affects the maximum possible simultaneous Notes client connections (sessions), size of caches, and server add-in task performance (because of less paging to disk).
如果通过DataGrid进行分页时返回了100,000个记录,那么针对每个请求会放弃99,975个记录(假设每页大小为25个记录)。
If 100,000 records are returned when you're paging through the DataGrid, 99,975 records would be discarded on each request (assuming a page size of 25).
如果您采取了这种方式,并且外部存储直到重新启动之后才可用,那么您的系统可能会出现崩溃(这取决于所分配的分页空间的大小)。
If you do this and the external storage is not available on a reboot, your system might crash (depending upon the amount of space allocated to paging).
这时要特别小心,因为如果配置不当,则可能导致4KB或64 KB页面大小的池过度分页。
Do this with extreme caution, because over configuring the system with 16-megabyte or 16-gigabyte pages can lead to excessive paging of 4-kilobyte or 64-kilobyte page size pools.
注意,64KB页面完全可以进行分页,并且64 kb页帧的池的大小是动态的。
Note that 64-kilobyte pages are fully capable of being paged and that the size of the pool of 64-kilobyte page frames is dynamic.
可以使用chps - s命令来动态增加分页空间的大小。
You can use the CHPS -s command to dynamically increase the size of a paging space. For example, if you want to increase the size of hd6 with 3 logical partitions, you issue the following command.
如果您想运行一个分页了内存磁盘并设置其大小为1650MB如上所述后续的下一步骤。
If you want to run a PageFile off the RamDisk and have set its size to 1650mb as mentioned above follow the next steps.
注意,分页单元会直观地将RAM划分成固定大小的页框。
Note that the paging unit visualizes ram to be partitioned into a fixed size of page frames.
分页部件认为所有的RAM都被分为固定大小的页帧(有时也叫物理页面)。
The paging unit thinks of all ram as partitioned into fixed-length page frames (sometimes referred to as physical pages).
增加缓冲区大小的代价很高,因为它来自不能交换到磁碟的未分页记忆体,所以尽可能让缓冲区愈小愈好。
Increasing the size of the buffer is expensive, as it comes from non paged memory that cannot be swapped out to disk, so keep the buffer as small as possible.
取得或设定值,这个值表示是否在回应特定事件(如页面大小变更)时自动在背景执行分页。
Gets or sets a value indicating whether pagination is performed automatically in the background in response to certain events, such as a change in page size.
