Servlet is persistent until it destroys. CGI requires additional processing on the server-side for every request, which can lead to slower performance and higher resource usage. It also needs to open a new database connection each time a request is made, which is again a slow and costly process. CGI has the disadvantage of doing server-side programming with platform-specific APIs. Servlet provide better performance that CGI in terms of processing time, memory utilization because servlets uses benefits of multithreading and for each request a new thread is created, that is faster than loading creating new Object for each request with CGI.
