Tomcat threads

[Andrew Hole <an...@gmail.com>]

Hello!

What's the value of Initial Number of Threads created on Tomcat startup?
Everytime it is necessary Tomcat creates another thread. What happens
after the processing end? The thread dies or becomes available for a
future processing?

Best regards

Whatever you configured on your <Connector> elements:
http://tomcat.apache.org/tomcat-6.0-doc/config/http.html
http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html

Hmmm... this was described in the 5.5 docs:
http://tomcat.apache.org/tomcat-5.5-doc/config/http.html

but descriptions of the maxSpareThreads and minSpareThreads attributes
seem to have disappeared from the 6.0 <Connector> docs.  They're still
in the source code, just not in the doc.  I wonder if their function was
supposed to be handled by the <Executor> element?  (As I recall, Remy M
recommended against using an <Executor>, at least for the time being,
due to performance issues.)
