[LoadUIWeb] Interpretting/Understanding Page Load Times

HI All,



Without boring you to death with details, I've been load testing an ASP.NET application. I've created a really simple scenario that simply logs in and waits on the home page.



When I load this with 10 VUs I get 'random' spikes in page load time. The summary reports figures such as



Max Page Load: 12.38s

Ave Page Load: 4.26s

Min Page Load:  0.43s



I don't understand how the same page can have response time between 0.4s and 12.38s



Can anyone help me get my head around this?



Thanks in advance
