What is the default queue size for apache tomcat in spring boot?

Question

What is the default request queue size in apache tomcat which is embedded in spring boot ?

Answer 1

As of spring boot version 2.7.2, this is set to 100 by default. You can use the following property to change it:

server.tomcat.accept-count=100

According to the documentation this is used to specify:

Maximum queue length for incoming connection requests when all possible request processing threads are in use.

To check for the version you're using, you can try replacing the version in this url & searching for acceptCount.
