<!--- Time an empty loop with this many iterations --->
<cfset tickBegin = GetTickCount()>
<cfloop Index = i From = 1 To = #iterationCount#></cfloop>
<cfset tickEnd = GetTickCount()>

What is the internal timer based on? Does it reset when the server reboots?

jrunrandy said on Dec 30, 2003 at 1:07 PM :

getTickCount is based on the Java method System.currentTimeMillis()

However, this value can vary, based on platform and OS and it's probably not a good idea to make anything depend on this value. In addition, CFMX returns this value as an int and CFMX 6.1 returns it as a String.

Also, the description on the CFMX page isn't great. See the 6.1 page for a better description: http://livedocs.macromedia.com/coldfusion/6.1/htmldocs/funct110.htm

See the JavaDocs for more information: http://java.sun.com/j2se/1.4.1/docs/api/
