在hypervisor和访客操作系统之间有通信机制,用以提高相互协作的性能和效率。
There is a communication mechanism between hypervisor and guest operating systems to improve performance and better efficiency with mutual cooperation.
尽管这样做提供很大的灵活性(即运行未更改的操作系统),但它的效率比较低(参见图1左边)。
Although doing so provides the greatest flexibility (namely, running an unmodified operating system), it does introduce inefficiency (see the left side of Figure 1).
首先,写一个全球个人电脑都容易收到感染的病毒会比去写一个很少人使用的操作系统病毒更为有效率。
For one, writing nastiness that the vast majority of the world's personal computers are susceptible to is a more efficient use of resources than writing the same evil for a sliver of the population.
调优意味着对系统增加内存、修改操作系统参数、加速Web或数据库服务器、提高代码效率或者这其中的一些组合。
Tuning might mean adding memory to a starved system, modifying operating system parameters, hastening the Web or database server, rewriting code for efficiency, or some combination thereof.
这里面临的一个问题在于,计算机操作系统已经实现了一定的成熟度和效率,我们甚至可以说,对操作系统的使用已经达到了收益递减点(Point of Diminishing Returns)。
Part of what’s going here is that the computer operating system has achieved a level of maturity and efficiency. You could even say that work on the OS has reached a point of diminishing returns.
浏览器内存方案可能比标准的操作系统内存功能更有效率,让浏览器更灵活的管理他的内存。
Browser memory schemes may be more efficient than standard OS memory functions, and can give the browser flexibility in the way it manages memory.
硬件RAID不依赖操作系统,具有比软件RAID更高的运行效率和容错能力。
Hardware RAID is not dependent upon operating system, having higher operating efficiency and fault-tolerant capability than software RAID.
开发实践表明,使用实时操作系统进行发动机控制系统的开发,能有效地提高开发效率。
The development practice shows that the efficiency of product development can be improved obviously with the use of real-time operating system.
与这些同类产品相比,本系统有以下几点优势:首先,大部份同类产品不是真正地对文件内容监控,因为他们解决不了效率问题。其次,同时支持多种操作系统平台的产品只有本系统。
Compared with these products, the system has the following advantages: First of all, for most similar products can't solve the problem of efficiency, they were not actually monitoring the documents.
仅管不如苹果操作系统的用户界面那么先进,它用于提高人们工作效率已经足够了。
Although not as advanced as Apple's OS UI, it was just good enough to get most people to become more productive.
操作系统内核体系结构的设计采用了建立在纳核层上的微内核结构,并在微内核的构建中融合了基于对象技术,克服了传统微内核结构消息传递机制效率低下的缺点。
The architecture of the kernel is a micro-kernel developed with objects and based on a nano-kernel. It overcomes the shortcoming of inefficiency of traditional micro-kernel.
目前的操作系统通常支持同步处理I/O请求,但因此产生的进程的阻塞和中断响应处理将对服务器处理I/O请求的效率产生负面影响。
Presently, most operation systems supply synchronous method to implement I/O requests, but in this case blocked processes and handling interrupts produce negative performance.
嵌入式操作系统选择的好坏是整个嵌入式系统运行是否稳定、可靠、执行效率高低的关键所在。
In the embedded system development process, the quality of underlying operating system is the key to the stability and efficiency of the entire embedded system.
