Tomcat maxThread config

Question

I was going through the documentation at https://tomcat.apache.org/tomcat-7.0-doc/config/http.html to understand maxThread and maxConnections. In a BIO setting the default value of maxConnections is same as maxThreads.

What happens if say in one of the requests, the program internally spawns say 30 threads to process a job faster. Does this 30 threads take up the count set by the maxThread? So if maxThread was set to 100, will that reduce it to 70?

Answer 1

The internally spawned threads won't take up the maxThreads. The maxThreads only limits the threads which created by tomcat connector.
