Understanding about Tomcat Thread Pool

Understanding about Tomcat Thread Pool
By default, Tomcat creates a bound thread pool for each connector (the maximum number of threads is 200 ). In most cases, you do not need to change this configuration (unless you increase the maximum number of threads to meet high load requirements ). However, Tomcat prefers to cache objects such as PageContext and tag cache in the thread-local context of each worker thread. For this reason, you expect Tomcat to turn off the thread to clear some memory. In addition, if each connector maintains its own thread pool, it is more difficult to set a maximum value (number of threads) based on the server's capacity. The answer to these questions is to use a shared executor.
