I am on the verge of finishing an application and I am starting to do some performance testing. One requirement sent to me by the executives is that the app must be able to support "250 simultaneous users" at a time.
My question is, what exactly constitutes "250 simultaneous users"? Is that supposed to mean the ability to support 250 people all hitting the submit button at precisely the same time? Or 250 people using the app at a given instance? Can CF realistically support that figure if the answer is "all at one time"? I mean, I guess the phrase is somewhat open to interpretation, but I was just wondering if there was some standard definitions in the performance tuning world that definitively answers what "simultaneous" is meant to be. Also, if I have the number of simultaneous requests set to 3 in my CF administrator, how does CF's queue hold up with 247 requests waiting? As a rule, is it flaky? What happens in a clustered environment (say 2 servers)? I know that's a lot of questions, but I'm trying to work on these skills, as they are as important as being able to write the CF code itself. As you can probably tell, I'm relatively new to detailed performance tuning. If it makes any difference in the answers, I'm using CF 4.5.2 on Solaris with Apache 1.3.6 as my web server. Thanks in advance, Dave. _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com ______________________________________________________________________ This list and all House of Fusion resources hosted by CFHosting.com.
