Sebb closed NET-499.
--------------------
> FTP transfer to mainframe extremely slow
> ----------------------------------------
>
> Key: NET-499
> URL: https://issues.apache.org/jira/browse/NET-499
> Project: Commons Net
> Issue Type: Bug
> Components: FTP
> Affects Versions: 3.2
> Environment: Windows and OSX
> Reporter: Denis Molony
> Fix For: 3.3
>
>
> FTPClient.storeFile() is incredibly slow. I have two example files, one FB
> (4MB) and one in ravel VB (94K) format. Under 3.1 both files transfer in less
> than a second (FB:328ms, VB:112ms). Under 3.2 the VB transfer takes 30,000ms,
> and the FB transfer takes too long to find out (> 15 minutes).
> I have checked the FB file on the mainframe after cancelling the transfer and
> it is always partly there. But the length varies, suggesting that it hasn't
> hit the same error each time.
> I have built two jar files, one with 3.1 and the other with 3.2. These jars
> are available. The code is as follows:
> {code}
> public class FTPTransfer
> {
> public static void transfer (String name, FTPClient ftp, File file) throws
> IOException
> {
> FileInputStream fis = new FileInputStream (file);
> long start = System.currentTimeMillis ();
> if (ftp.storeFile (name, fis))
> System.out.print ("File transferred");
> else
> System.out.print ("Transfer failed");
> System.out.printf (" in %d ms%n", (System.currentTimeMillis () - start));
> fis.close ();
> }
> public static void main (String[] args)
> {
> File file1 = null;
> File file2 = null;
> if (System.getProperty ("os.name").toLowerCase ().startsWith ("mac"))
> {
> file1 = new File ("/Users/Denis/comtest/DENIS-018.SRC"); // ravel
> file format
> file2 = new File ("/Users/Denis/comtest/MOLONYD.NCD"); // FB252
> format
> }
> else
> {
> file1 = new File ("D:/comtest/DENIS-018.SRC"); // ravel file format
> file2 = new File ("D:/comtest/MOLONYD.NCD"); // FB252 format
> }
> FTPClient ftp = new FTPClient ();
> ftp.addProtocolCommandListener (new PrintCommandListener (new PrintWriter
> (System.out), true));
> try
> {
> ftp.connect ("server");
> int reply = ftp.getReplyCode ();
> if (!FTPReply.isPositiveCompletion (reply))
> {
> ftp.disconnect ();
> System.err.println ("FTP server refused connection.");
> System.exit (1);
> }
> ftp.login ("user", "pw");
> FTPFile[] files = ftp.listFiles ();
> System.out.printf ("%nListing contains %d files%n%n", files.length);
> ftp.setFileType (FTP.BINARY_FILE_TYPE);
> ftp.setFileStructure (FTP.RECORD_STRUCTURE);
> transfer ("TEST.VB", ftp, file1);
> ftp.setFileStructure (FTP.FILE_STRUCTURE);
> transfer ("TEST.FB", ftp, file2);
> ftp.logout ();
> }
> catch (IOException e)
> {
> e.printStackTrace ();
> }
> finally
> {
> if (ftp.isConnected ())
> {
> try
> {
> ftp.disconnect ();
> }
> catch (IOException ioe)
> {
> }
> }
> }
> }
> }
> {code}
