> Thanks in advance, > Adam Howitt I wouldn't imagine it would be terribly difficult to test the theory... <cfset starttime = getTickCount()> <cfloop index="x" from="1" to="10000"> <cftry><cfset y = x> <cfcatch></cfcatch></cftry></cfloop> <cfset ms = getTickCount()-starttime> <cfoutput>normal time = #ms# milliseconds</cfoutput> <cfset starttime = getTickCount()> <cfloop index="x" from="1" to="10000"> <cftry><cfset y = x/0> <cfcatch></cfcatch></cftry></cfloop> <cfset ms = getTickCount()-starttime> <cfoutput>error time = #ms# milliseconds</cfoutput> I don't know if I'd describe it as "on its knees" but raising an error definately does require a few extra cycles... This is a pretty crude test tho -- if you really wanted to know the genuine impact, you'd set a load-testing tool like the MS web stress analyser against the application. s. isaac dealey 954.522.6080 new epoch : isn't it time for a change? add features without fixtures with the onTap open source framework http://www.fusiontap.com http://coldfusion.sys-con.com/author/4806Dealey.htm ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
