How does ERS FTP improve performance?
It can take advantage of the performance-tuning capabilities of the underlying Apache 2.0 structure. You can choose the balance between performance and scalability by picking the desired Apache processing module (pre-fork, threaded, hybrid). Requests are handled from a pool of workers instead of starting a process for each request. How are Apache HTTP and Tomcat integrated in ERS? Integration between Apache and Tomcat is provided in ERS. In older versions of Apache mod_jk was the most common method of forwarding requests to Tomcat from Apache. With Apcahe 2.2 the mod_proxy family of modules has become the recommended choice due to its simplicity and ease of troubleshooting. SpringSource provides both mod_proxy and mod_jk and supports both methods.
