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. I've timed almost everything, including the POE
state machines. I still see relatively fast processing (on the order of
10ms) speed from POE.
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.
