I have searched for exact documentation on this, and I always find
conflicting info. Therefore I am reaching out to this list. I have the
following info and questions:

- we are running tomcat 5.5.20
- we have the following configs in server.xml:
      <Connector port="8009"
         enableLookups="false" redirectPort="8443" debug="0"
         maxThreads="750" minSpareThreads="100" maxSpareThreads="250"
         acceptCount="100" connectionTimeout="5000"
tomcatAuthentication="
         false"

- we have extra capacity (mem, cpu, etc.) on the servers, yet tomcat is
hitting connection limits
- we feel that tomcat can serve more, so what do we tune to make it do so?
  - maxThreads?
  - minSpareThreads?
  - maxSpareThreads?
  - acceptCount?


Honestly, I would rather love an exact definition of what each of those
would do to the tomcat server if tweaked. Knowing that would be nirvana for
tuning.
