    摘要： A method and an apparatus for characterizing performance of a device based on user-perceivable latency. To characterize device performance, a value of a metric may be computed from latencies of operations performed by the device. In computing a value of a metric, latencies may be treated differently, such that some latencies perceivable by a user of the device may have a greater impact on the value of the metric than other latencies that either are not perceivable or are perceived by the user to a lesser degree. Such a performance metric based on user-perceivable latency facilitates identification of computing device that provide a desirable user experience.

    摘要： A proactive, resilient and self-tuning memory management system and method that result in actual and perceived performance improvements in memory management, by loading and maintaining data that is likely to be needed into memory, before the data is actually needed. The system includes mechanisms directed towards historical memory usage monitoring, memory usage analysis, refreshing memory with highly-valued (e.g., highly utilized) pages, I/O pre-fetching efficiency, and aggressive disk management. Based on the memory usage information, pages are prioritized with relative values, and mechanisms work to pre-fetch and/or maintain the more valuable pages in memory. Pages are pre-fetched and maintained in a prioritized standby page set that includes a number of subsets, by which more valuable pages remain in memory over less valuable pages. Valuable data that is paged out may be automatically brought back, in a resilient manner. Benefits include significantly reducing or even eliminating disk I/O due to memory page faults.

    摘要： Indexing documents is performed using low priority I/O requests. This aspect can be implemented in systems having an operating system that supports at least two priority levels for I/O requests to its filing system. Low priority I/O requests can be used for accessing documents to be indexed. Low priority I/O requests can also be used for writing information into the index. Higher priority requests can be used for I/O requests to access the index in response queries from a user. I/O request priority can be set on a per-thread basis as opposed to being set on a per-process basis (which may generate two or more threads for which it may be desirable to assign different priorities).

    摘要翻译： 使用低优先级I / O请求执行索引文档。 该方面可以在具有对其归档系统的I / O请求支持至少两个优先级的操作系统的系统中实现。 低优先级I / O请求可用于访问要索引的文档。 低优先级I / O请求也可用于将信息写入索引。 较高优先级的请求可用于从用户的响应查询中访问索引的I / O请求。 可以在每个线程的基础上设置I / O请求的优先级，而不是在每个进程的基础上进行设置（可能会生成两个或更多个可能需要分配不同优先级的线程）。
