URLConnection question..how to increase performance?

Question

Hi,
I am trying to download a text file using FTP and display it in the browser. The code below is within a JSP page.
My problem is that it works with small files very quickly, but as soon as the file size is large, it is VERY VERY slow. A file which normally takes 30-50 seconds over FTP takes about 25 MINUTES if i use the code below.
How can I increase the speed...?? Should I used different bufferedreaders?
I want to preserve the /n/r of the original file so that the file is readable in the browser.
Thanks for any help....I am new to Java..
               URL theUrl = new URL("ftp://"+strHost + strFilePath + strFileName);
               URLConnection uc = theUrl.openConnection();
               InputStream content = uc.getInputStream();
               BufferedInputStream in = new BufferedInputStream (content);
               LineNumberReader lnr = new LineNumberReader (new InputStreamReader (in));
               String tempStr = "";
               String str = "";
               while ((tempStr = lnr.readLine()) != null) {
               str += (tempStr);
                    %>
                    <%=tempStr%><BR>
                    <%tempStr = "";
                    %>
               <%
               in.close();
               lnr.close();

Hi, thanks for all your suggestions. Here is what i have used finally and it is remarkably fasssstttt.....
It has solved all my problems. I am able to download a text file of over 2MB and display it under 20 seconds.
               URL theUrl = new URL("ftp://"+strHost + strFilePath + strFileName);
               URLConnection uc = theUrl.openConnection();
               BufferedReader reader = new BufferedReader(new InputStreamReader(uc.getInputStream()));
               String line;
               while( (line= reader.readLine()) != null){
                         line += "<BR>";%>
                    <%=line%>
               <%}
               reader.close();
