RE: performance of tomcat 8 is less than tomcat 6
Hi Christopher,
I am using simple HelloWorld servlet. Which will give "Hello World!" as
response. There is no business logic in the servlet. Same code is executing on
both the version of tomcat.
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("");
out.println("");
out.println("Hello World!");
out.println("");
out.println("");
out.println("Hello World!");
out.println("");
out.println("");
}
}
