You can turn on the detailed verbose GC options in the 1.4.x VM and find out exactly what is happening. Also if the call is taking two minutes take a few thread dumps in the middle of the call. The stacks will tell you exactly what the thread is doing during that time. By taking a few 10-15 seconds apart you can watch it work.

This sounds like garbage collection impacting your response times although two minutes is outrageously high. I expect that you could tune your system to level out response times - there are articles on mm.com for this (and Nimer can definitely point you at some good resources).
