POE performance issue.

Hello, I am new to the POE architecture and intricacies. I am maintaining a code developped by such an architecture,

Client<->SOAP<->Server (scheduled by POE).

Request is delivered from client to server through SOAP and POE queues the requests and handles them. The problem is we are getting extremely poor performance from this message flow. I've tested each individual component but POE (the code is almost unreadable partially due to my unfamiliarity with POE). Each component is responding to request blazingly fast (on the order of millisecond). However, the POE kernel is queueing up all the requests before they are sent to the actualy request handler and the request handler are not efficiently used. For some reason, the response from the request handlers are not picked up by the POE kernel after 60ms.

Thus my problem requires a good understanding of the inner working of POE. Someone said POE is designed to be responsive on the order of second. And I cann't expect better performance than that. Is this statement true?

If you can provide some pointers on understanding POE or general POE performance tuning tips, I'd really appreciate them.
