Because when you do it in cf, you are forcing it to execute (do math) however long you do the function for. When you are calling the java function, it calls some method that wakes it up after a certain time, but does not use any cpu..

Out of curiousity, why does this affect the CPU any different than the JAVA thread? The process still has to wait the same amount of time, doesn't it? Why call another external process? Wouldn't that be more overhead? I don't know much about Java, so my questions may sound stupid, but I think an explanation would be helpful to those on the list who also don't understand why this is bad. It's not an endless loop and it's controlled by the input. You could add a max amount in there if you wanted to avoid wait time's longer than a specified time.

Ouch, don't do that. This will spike your CPU, looping frantically until the given time comes up. The java thread sleep method is much better. Here's an already packaged function i pasted together a couple years ago. www.cflib.org/udf.cfm/sleep -nathan strutz [EMAIL PROTECTED] wrote: > Here's a way as a UDF: > > <cfscript> > function WaitMS(ms) { > var startms = getTickCount(); > var endms = startms + ms; > while (endms GT getTickCount()); > } > </cfscript> > > Dave > > On 22/08/05, Troy Simpson <[EMAIL PROTECTED]> wrote: > >>I know this is not normally needed for a ColdFusion Application >>because most people want their apps to run fast. >> >>But I have a need to put a wait period in my code.
