3. use LR or JMeter send 5 requests to the serlvet above
I'm going to guess based on the Tomcat 7 documentation:
request 1 gets executed and sits in your doPost for 60 seconds
request 2 consumes the minSpareThread
request 3 consumes the acceptCount
Per documentation, connections 4 and 5 are dropped immediately.
That is almost right except that there should not be a spare thread at
step 2 since maxThreads includes any spare threads.
Yep, that's what I would expect as well. I was just trying to
rationalize the third accept.
I agree, I would think that 1 would be served, 2 would wait, and 3-5
would be dropped.
I'd expect request 2 to use the accept count and 3, 4 & 5 to be dropped.
There may be an off-by-one error somewhere or it could just be an
artefact of how the limit is enforced.
Please read the following and see if my interpretation is reasonable:
http://tomcat.apache.org/tomcat-7.0-doc/config/http.html
Pay particular attention to the Introduction section.
If I have the particulars wrong, hopefully someone will come along and
correct me.

I guess some tests are in order?
