FTPClient.storeFile is very slow
I am using commons-net FTPClient utility to transfer files, sizes upto 50MB.
When i try to transfer the file using the command prompt, the file transfers
in 5 seconds. But when i use the FTPClient Utility, it takes about 1 minute.
I set the BufferSize etc to about 8MB, but the result is the same. Can
somebody suggest how i can improve the upload performance?
The code snippet is below
boolean success = false;
try {
connect();
try {
ftp.setFileType(FTP.BINARY_FILE_TYPE);
ftp.setRemoteVerificationEnabled(false);
StringTokenizer st = new StringTokenizer(destination, "/");
while (st.hasMoreElements()) {
String dir = st.nextToken();
ftp.makeDirectory(dir);
ftp.changeWorkingDirectory(dir);
}
ftp.setBufferSize(100000);
logger.info("Start Time For Sending Track"
+ fileName
+ " "
+ DateFormatUtils.format(Calendar.getInstance().getTime(),
"yyyy-MM-dd hh:mm:ss"));
File f = new File(source + File.separator + fileName);
FileInputStream fis = new FileInputStream(f);
success = ftp.storeFile(fileName, fis);
fis.close();
logger.info("End Time For Sending Track"
+ fileName
+ " "
+ DateFormatUtils.format(Calendar.getInstance().getTime(),
"yyyy-MM-dd hh:mm:ss"));
} catch (Exception e) {
if(e.getMessage().startsWith("Host attempting data connection")){
success = true;
}
logger.severe(e);
try {
ftp.disconnect();
} catch (IOException e2) {
// TODO Auto-generated catch block
logger.severe(e2);
}
}
} catch (Exception e) {
success = false;
}

Could you add logging to see exactly where the time is spent?
