Performance optimization is an area of concern in Tomcat that should be made better. I think the performance optimization has to be improved for monitoring, management of logs, load balancing, and containerization support. I think there is a need for some enhancement in the product's security as I work in my company's security area. If someone asks me about Tomcat from a performance perspective, I would say that tuning thread pools, caching, and compression needs improvement. In general, Tomcat should provide regular updates with respect to security. I think Tomcat is a good and lightweight tool, but it needs improvement in areas like security and performance. Maybe a web application firewall or WAF products can be considered to protect the applications on websites, which is again some improvements needed from a security perspective. If you ask me about the feature and monitoring and management of logs, which are generally areas related to APM, needs improvement. Even the alerts provided by the tool need improvement. Some simplified configurations and enhanced clustering can be considered for improvement in the product.
