查询词典 memory swapping

In fact systems requiring that level of performance simply lock programs in memory … swapping should never occur.

事实上，系统要求的性能水平，根本锁程式在记忆体中…交换应该永远不会发生。

The result is a significant decrease in performance as requests for memory lead to the so-called "swapping" of memory.

由于内存请求导致所谓的内存交换，造成系统性能大幅度下降。

It prevents excessive memory swapping and makes sure that a certain amount of memory isalways available, which results in performance increase and lower response times, especially if youare running many applications at the same time and tend to switch between them quite often.

该软件可以预防过度的内存交换并且可以确保一定数量的内存维持在可使用状态。这就可以确保性能的提升和较低的响应时间，除非你正在同时运行许多应用软件并且有在这些程序之间频繁切换的趋势。

This happens because if free memory falls below a minimum value, the host operating system continually frees up memory by swapping to disk to maintain that amount of free memory.

这种情况是因为空余的内存降低到了一个最小的数值，这时主机要不断地使用磁盘交换数据来释放内存。

The operating system uses a portion of the hard disk as virtual memory,swapping data and instructions beween the hard disk and physical memory.

物理内存用于储存诸如操作系统、视频数据及计算机用于运行程序的指令和数据之类的内容。

Sites which need to serve more than 256 simultaneous requests may need to increase MaxClients , while sites with limited memory may need to decrease MaxClients to keep the server from thrashing (swapping memory to disk and back). More information about tuning process creation is provided in the performance hints documentation.

站点在需要处理大于256个并发的时候，需要增加MaxClients指令，同时，站点在有限的内存下需要减少MaxClients的值以便保持服务器不崩溃（太多的MaxClients需要从磁盘中进行内存的交换）更多的关于如何调整子进程创建的信息请参照性能建议文档。

In our testing, when the app isn't using a large data set (one that would otherwise require memory swapping), the speedup due to running in 64-bit mode is around 8-12%.

如果有的话，在64bit模式可以一个指令算完，32bit要拆开算在合起来，最少要四次以上，这样才会有速度的差别。

Protected mode allows for 16M of memory but is also capable of protecting the operating system and programs from accident and deliberate destruction by users, a feature that is absent in the single-user 8088/8086 Virtual memory is a way of fooling the microprocessor into thinking that it has access to an almost unlimited amount of memory by swapping data between disk storage and RAM.

在保护模式下系统可用16M的内存寻址并且可防止操作系统或程序被用户不经意或故意破坏。这个特征是单用户8088/8086所不具备的。所谓虚拟内存就是通过在磁盘存储器与RAM中交换数据将微处理器骗过，使之认为它有无限大的内存寻址空间。

To increase the recording of FLIM time series we employed a memory swapping technique that reads out the data of one recording step during the acquisition of the next one.With parallel operation of two TCSPC modules we were able to record FLIM time series at a rate of 2 images per second.

为增加FLIM时间序列记录，利用存储交换技术，在采集下一个光子期间读取正在记录的数据，使用两个平行TCSPC模块，可以每秒两幅图像记录荧光寿命时间序列。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
