FasterStaticPageServlet

import java.io.*;

import jakarta.servlet.ServletException;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.annotation.WebServlet;
import jakarta.servlet.http.HttpServletRequest;

@WebServlet(urlPatterns = { "/fastpage" })
public class FasterStaticPageServlet extends HttpServlet {


    protected void doGet(HttpServletRequest request,
                         HttpServletResponse response) throws ServletException, IOException {

        var target = request.getParameter("target")  != null ? request.getParameter("target") : "page_1";


        response.setContentType("text/html;charset=UTF-8");
        PrintWriter pw = response.getWriter();
        // atualize a URL
        var pageFilePath = "/home/murilo/workspaces/personal/DSW1/AloMundoMVN/pages/" + target + ".html";

        FileReader fr = new FileReader(pageFilePath);
        fr.transferTo(pw);
        fr.close();
        pw.close();

    }

}

StaticPageServelet

@WebServlet(urlPatterns = { "/page", "/p" })
public class StaticPageServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request,
                         HttpServletResponse response) throws ServletException, IOException {

        var target = request.getParameter("target")  != null ? request.getParameter("target") : "page_1";


        response.setContentType("text/html;charset=UTF-8");
        PrintWriter pw = response.getWriter();
        // atualize a URL
        var pageFilePath = "/home/murilo/workspaces/personal/DSW1/AloMundoMVN/pages/" + target + ".html";
        BufferedReader reader = new BufferedReader(new FileReader(pageFilePath));
        reader.lines().forEach(pw::println);
        reader.close();
        pw.close();



    }

}

Na versão otimizada, minha abordagem foi reduzir o tempo de leitura e copia do arquivo transferindo-o todo de uma vez utilizando o método transferTo().

Utilizando o script para teste obtive uma média de 387,26ms contra 437,23ms, o que representa um ganho aproximado de 11,5% no tempo de resposta.
