prefetch造句
(1) Clean out the Windows prefetch folder to improve performance.
(2) When the prefetch quantity is changed.
(3) After the prefetch size has been changed.
(4) Large pages also improve memory prefetching by eliminating the need to restart prefetch operations on 4KB boundaries.
(5) The Workers can be used to prefetch data or perform other ahead-of-time operations to provide a much more lively UI.
(6) Note that if the code asks to prefetch an already-fetched page, the implemented logic avoids making unnecessary, redundant calls to the server.
(7) When receiving and recognizing the prefetch directive, a hardware prefetcher associated with the target processor may issue a request to the system memory to prefetch data to the cache.
(8) Prefetch – Cache files at boot time ( optimal ).
(9) Listing 6 is an example of a helper function that uses a wrapper over the built-in function (from ./linux/include/linux/prefetch.h).
(10) PREFETCH: It is a method that allows DB2 to read the data in advance to prevent wait times while the data is being retrieved.
(11) The prefetch directive may be sent along with system interconnection transactions or sent as a separate transaction to devices including the target processor in the system.
(12) Even Better Prefetch Paths: We made the prefetch path engine (eager loading) even smarter so it now knows more ways to optimize the queries it has to create.
(13) But be careful: Don't go overboard and prefetch everything in sight, or you'll make things worse!
(14) This recovery process instantly begins to prefetch dirty pages from the centralized buffer pool into its own local buffer pool.
(15) I/O servers are used on behalf of the database agents to perform prefetch I/O and asynchronous I/O by utilities such as backup and restore.
(16) In DB2, I/O Servers are threads or agents that perform prefetch I/O and asynchronous I/O on behalf of the database worker threads.
(17) Prefetchsize determines the number of pages read from disk during a prefetch request and is usually set to a multiple of the extentsize.
(18) Performance needs to be considered to set important database parameters such as buffer-pool page size, extentsize, and prefetch size.
(19) Also, check out my list of web accelerators, which are programs that try to prefetch and cache the sites you are going to visit.
(20) When DB2 does not have an index in the appropriate order for sort avoidance or when DB2 uses any index the LIST PREFETCH way, then an ORDER BY will most certainly cause a data sort.
(21) If DB2 were to use the index the nontraditional, LIST PREFETCH way, the rows would not come back in the order of the index, but rather in the order of the table.
(22) Tests prove that the average data transfer rate of the RAID which uses the read prefetch policy increases! by 60 % , meeting the high requirement of I/O performance in digital systems.
(23) And finally, whenever a user picks a country and region, prefetch the first two pages just in case, as shown in Listing 4.
(24) Three basic load balance strategies on mapping applications onto GPU are presented: Prefetch, stream computing, task division.
