Hi

What you are seeing the is the server starting up some of the time
(hence long response times) and sometime hitting a running server
(short response times)

Servers may recycle very quickly (ie in as little as 30 secs)

A typical server startup time for django and some other frameworks is
2-3 secs
You can see this in you admin console logs


Java will no doubt exhibit the same thing
