Original address Statement: This article with its own understanding, not fully translated according to the original Prefetch is pre-loaded, we load the required resources before the user needs them.With the browser cache, why do I need to preload? The user may have visited the site for the first time, and there is no cache at this time The user may have emptied the cache The cache may have expired and the resource will r

In HTML5, there is a very useful but often overlooked feature, which is pre-loading (prefetch), which has the following principles:Use the browser's idle time to download the user-specified content first, and then cache it, so that the next time the user loads, it will be removed directly from the cache, the efficiency is fast.For example: to preload a page, you can:Xml/html Code But if it is Google, use a different name, namely:Xml/htm

Describes how to use the prefetch preload function of the rel attribute in HTML5, html5rel In HTML5, a very useful but often overlooked feature is prefetch. Its principle is:The browser's free time is used to download the content specified by the user and then cache the content. This way, the user can directly obtain the content from the cache next time the user loads the file, and the efficiency is faster.

A simple record: today, when debugging the dormant code, we encountered a very strange problem. During the wake-up process, we encountered a problem that we did not see oops. It seems that the operation is illegal, and the CPU enters the abnormal state. Bad mode in prefetch abort handler Detected Internal error: Oops-bad mode: 0 [#1] Modules linked in: CPU: 0 PC is at serial_pxa_resume + 0x38/0x58 LR is at uart_resume_port + 0x1d8/0x1e4 PC: [SP: c78c1

Pre-fetching engine technology, it is through the server to the current Web page technical analysis, determine which links will be the user next click on the target, and then read the link in advance of some CSS and other large-capacity picture video files; Once the user clicks on the preloaded link, the user simply waits for a short time to download the picture ( It may be that the Sogou has been typeset, just wait for the picture to download, without the need to download the entire page as bef

Hibernate optimization Crawl (select the bulk prefetch data of the crawl strategy) hibernate execute the SQL SELECT statement to load the object into memory. If you load an object, you perform a single or several select, depending on the number of tables involved and the crawl strategy you are using. Your goal is to minimize the number of SQL statements and simplify the SQL statements to maximize query efficiency. You do this by applying the best craw

Sometimes you may use SQLPLUS spool table data. How can you speed up the spool? SQLPLUS has a row prefetch Option In SQLPLUS, the default arraysize is 15. SQL> show arraysizeArraysize 15 It indicates that only 15 rows of records are transferred from the Oracle server to the client (SQLPLUS) at a time. Of course, JDBC and WEBLOGIC also have row prefetch. For example: SQL> select * from test where owner = 'ad

For a traditional page model, the Pull + render model for the data is as follows:In the head section of the page, use JSONP to pre-pull the CGI resource and then, after the resource is loaded, check that the prefetch data has been returned, and if it is returned, it is rendered directly with the data (avoiding the two refreshes caused by rendering the cached data first and then rendering the CGI data), otherwise the cached data is rendered.For the abo

Since you are limited to integral expressionsExp, You shoshould use constructions such If (_ builtin_ct (PTR! = NULL, 1) Foo (* PTR ); When testing pointer or floating-point values. Well, in one sentence, compilation optimization is used to make code instruction prefetch more efficient. For specific test code, refer to the following URL:

Connect back: http://blog.csdn.net/pennyliang/archive/2011/03/08/6231709.aspx There is no room for optimization in the method of using complex commands. The optimization work relies entirely on Intel engineers and uses streamlined commands to expand the cycle. More techniques can be used, including prefetch, NT, I have not said much about the previous article in the non-Temp series. In addition, Registers starting with R8 are used here, which are newl

PHP provides functions such as filesize, copy, unlink, and so on, but does not provide functions such as dirsize, Copydir, Rmdirs and Other folder operations (RmDir can only delete empty directories). So you can only write these functions manually, and the main trick is to decompose the problem by layer by recursion until it breaks down into the least-boy problem that can be solved directly. ==================== View
