title: Long Application Startup times on WebSphere Application Server 6.1 FixPack 21
body: <p>I'm seeing that my application startup times have grown long after I've migrated from WAS FixPack15 to FixPack 21. By application startup time, I mean the interval between the log statements :</p>
  
  <p>WSVR0200I: Starting application</p>
  
  <p>AND</p>
  
  <p>WSVR0221I: Application started</p>
  
  <p>This interval was less than 10 sec on FP 15, but it is 2 min on FP 21. Nothing has changed, except for the new fix pack. 
  However, if I bounce my WAS instance, and then start the application, the start up time was short (10 sec). But on occasions when I don't bounce my WAS instance, my application startup on FP 21 takes 2 min where it used to take 10 sec on FP 15.</p>
  
  <p>I was wondering if any of you have any pointers about how to troubleshoot this issue.</p>
