how to improve imac performance

In order to improve the performance of ASP program, people often use the data cached in application, but you modify the database how to let application update, this article gives you a reasonable solution. Class wawa_app_getrowsPublic Function wawa_get_list (strapp,strconn,strsql)'********************************' Function: Extract the array from the application, and then call the Wawa_get_rows () function

the number of records in the table(1) To get the number of records in a table, we typically use the following SQL statement:SelectCount (*) from Dbo.ordersThis statement performs a full table scan to get the number of rows.(2) But the following SQL statement does not perform a full table scan as it can get the number of rows:SELECT rows from sysindexes WHERE ID =object_id (' dbo. Orders ') and indid Avoid repeating calls to functions in stored procedures, triggers, functions, and batches, and y

by fragment caching is the same as that used by page-level output caching, but it is applied to user controls (. ascx files) instead of Web forms.The user control also supports the attribute VaryByControl, which changes the control cache based on the value of the server control in the. ascx file. If VaryByControl is specified, You can omit VaryByParam. If all pages use the same user control, you can set the value of Shared to "true ".Cache the user control for 60 seconds, and create a separate

1. Storage Partition the hard disk into NTFS format. NTFS is faster than FAT32, And you can view the size of your data file. You can use multi-database files for 1 GB or more, in this way, the access load can be distributed to multiple physical hard disks or disk arrays. 2. tempdb Tempdb should also be placed on a separate physical hard disk or disk array. We recommend that you place it on RAID 0 so that it has the highest performance. Do not set the

Using Local variablesTry to use local variables instead of global variables: Ease of maintenance, improved performance, and memory savings.Use local variables to replace variables

By using some auxiliary tools to find bottlenecks in your program, you can optimize the code for the Bottleneck section. There are generally two scenarios: optimizing the code or changing the design method. We typically choose the latter because not calling the following code can improve program performance better than calling some optimized code. A well-designed program can streamline code to

The Windows 8 system is more resource-saving than earlier Windows 7, Windows Vista systems, and even with the same hardware conditions, its speed and graphical display will be greatly improved, so we can try to troubleshoot the hardware problem by optimizing the startup entry, stopping the service, Upgrade drive to improve the slow running of the computer. First of all, we can adjust the visual effect to the "best

How to get Oracle experiment to improve performance when not experimenting--win7 exampleModel: ThinkPad E431System: WIN7The experiment uses a notebook when the database is not used. It is recommended that you shut down Oracle so that it frees up the resources it consumes.Oracle Software is very resource-intensive, and if the performance of the PC hardware is poor
