Some benchmarks... CF5 P550 ArraySort - Averages 90ms <cfset tList = "10,5,3,6,1,7,8,9,2,4"> <cfset tArray = listToArray(tList)> <cfloop from="1" to="1000" index="i"> <cfset rs = arraySort(tArray, "numeric")> </cfloop>
ListSort - Averages 210ms <cfset tList = "10,5,3,6,1,7,8,9,2,4"> <cfloop from="1" to="1000" index="i"> <cfset rs = listSort(tList, "numeric")> </cfloop> ArraySort is the clear winner, but the performance difference in the grand scheme of things is negligible. For the curious cfscript made absolutely no difference in the times. jon ----- Original Message ----- From: "Raymond Camden" <[EMAIL PROTECTED]> To: "CF-Talk" <[EMAIL PROTECTED]> Sent: Monday, December 03, 2001 8:53 AM Subject: RE: ArraySort > What logic do you base this on?
