Start by explaining which parts of SQL Server memory footprint are made up of. The memory consumed by SQL Server consists primarily of three parts: data caching (database buffer), execution caching (Procedure cache), and SQL Server engine programs. The caching of SQL Server engine programs is generally relatively small, and the primary focus of our memory tuning is on the control of data caching and execution caching. This article mainly describes the
When we design the Web page, we often have to make some small icons to meet the actual needs. Fireworks MX Since as one of the Three Musketeers, in this respect naturally has its own unique place. Today we'll use the "big footprint" icon as an example to illustrate how to easily design a Web site icon using fireworks.
Step 1:
Open Fireworks MX, using the menu command file-new, create a new file with a width and height of 300 pixels and a backgro

High memory Cause Analysis:
In the 360 browser 3.x multi-process framework, memory footprint is higher than the single process, but the advantage is that the Web page will be completely free of resources after the page is closed. In the 360 browser 3.x mixed process framework, memory footprint is higher than the single process, but the advantage is that the Web page after the closure of a better release of

Chrome browser can be restarted to release a lot of memory, here is a convenient way to make a simple bookmark to quickly restart the Chrome browser, and restart after the chrome can automatically restore just browse all the tabs, one key!
Tips for releasing memory from the Chrome browser:
1. Use the shortcut key Ctrl+d (Windows)/Cmd+d (MAC) on any tab, open the Bookmark page, and click "Modi

Should be looking for hash, ask the node, and then go back and ask the inside node, the last number of more and more, but I do not understand how to run so much more than a minute to have 600,000. That is to say, there are so many objects in memory that were not released. When this memory footprint is reached, the basic wil
introduces the format of the Smaps file, By analyzing the Smaps file we can learn more about the usage of process physical memory, such as how much space the Mmap file occupies, how much space is consumed by dynamic memory, how much space the function call stack consumes, and so on.
Two concepts about memory
To understand the output of the top command with regard to memory usage, we must first figure out the two concepts of virtual memory (fictitious Memory) and resident memory (resident Memory
. This consumption is mainly sortlist insertion, internal sorting and removal of records. When it comes to the choice of sortlist or sortdictionary, and then find some information, sortdictionary in the internal use of red-black tree implementation, sortlist using an ordered array implementation, in the internal sort are O (logn) under the premise , the time complexity of Sortdictionary O (LOGN) inserts and deletes elements is better than sortlist, but sortdictionary consumes more memory than so
index, and if the condition is like '%abc ', MySQL will not use the index.ü In an order by operation, MySQL uses the index only if the sort condition is not a query condition expression. However, in queries involving multiple data tables, even if an index is available, those indexes have little effect in accelerating the order by operation.ü If a data column contains many duplicate values, it will not be very effective even if you set up an index for it. For example, if a data column contains t
