ASP display the page execution time method _ application Skill

In an ASP program, it is very easy to calculate how much time a page will take to start from execution to execution. We know that ASP is an interpreted language, that is, its execution process is from the beginning of the page to the end of the page, we only need to calculate a time difference can get the page execution.
Below see how to achieve, is divided into three steps!
First step: Define a start time variable at the head of the page and get the current time

<%
Dim startime
startime = Timer ()
%>

Step two: Define a variable at the end of the page, and get the current time

<%
Dim endtime
endtime = Timer ()
%>

Step three: Calculate two time difference, and output the page
Current page Execution time: <%=formatnumber ((endtime-startime) * 1000, 3)%> ms
Is it simple? The full instance code for the ASP page execution time is given below:

<% @LANGUAGE = "VBSCRIPT" codepage= "936"%>
<%
Dim startime startime
= Timer ()
%>
< ! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
 
 

The above is the ASP output page execution time method, the main three steps, the purpose of this test is to verify that the page is slow to open the reason, I hope to understand this aspect of learning help.
