First, performance parameters:
1, throughput
2, response time
3, execution time
4, scalability
Second, performance factors:
1, ASPX execution environment
2, write code logic
Third, improve performance method:
1. Avoid unnecessary operations. For example: use ispostback in Page_Load;
2, try to minimize the use of server-side controls
3. Close unnecessary page session and control ViewState <% @ Page EnableSessionState = "false"%>
4, disable VB and JSP dynamic type <% @ page language = "vb" strake = "true"%>
5, use stored procedures
6, use datereader instead of DataSet
7. Close the Debug mode of ASP.NET
8, use the Output Cache buffer using ASP.NET
<% @ OutputCache Duration = 60 VarybyParam = "None"%>
<% @ Outputcache duration = 60 varybyparam = "TextBox1, TextBox2"%>
Explanation: Duration is the expiration time of setting Cache;
VarbyParam is the setting of whether or not the parameter is changed, and all parameters when NONE uses the same cache. When settings TextBox1, the different values of TextBox1 are cached separately; when there are multiple parameters, the cache is combined;
9, do not use the Exception control program process
Try
{
Result = 100 / NUM;
}
Catch (Exception E)
{
Result = 0;
}
IF (Num! = 0)
Result = 100 / NUM;
Else
Result = 0;
Fourth, buffering classification:
1 Page buffer: Different buffer processing according to VarbyParam.
2 Squares: Use the page buffer in the page control. When you use the same page control multiple times in a page, you need to perform different buffer processing according to VarbyControl.
3 Data buffer: cache (range is like Application, all users)
Cache.Insert ("MyData", Source, Null, New Cached "))));
Cache.Insert ("MyData", Source, Null, DateTime.now.addhours (1), Timespan.zero;
Cache.Insert ("MyData", Source, Null, DateTime.maxValue, Timespan.fromminutes (20));
