Yes, in did, the client closes the connection. But it looks like the reason of it
that reply from server sent 15sec after request is arrived. The filter itself took
max 800ms. Any ideas how to trace where rest of the time was spent?
Looking at the requests log I can see that request processing is not equally distributed.
Some connections processed quite active, while others are not. Is there a way how I can see
selector threads activity?
