我正在使用Apache Commons FTPClient上传大文件，但是传输速度只是使用WinSCP通过FTP传输速度的一小部分。如何加快转移速度？

    public boolean upload(String host, String user, String password, String directory, 
        String sourcePath, String filename) throws IOException{
    FTPClient client = new FTPClient();
    FileInputStream fis = null;
    try {
        client.connect(host);
        client.login(user, password);
        client.setControlKeepAliveTimeout(500);
        logger.info("Uploading " + sourcePath);
        fis = new FileInputStream(sourcePath);
        //
        // Store file to server
        //
        client.changeWorkingDirectory(directory);
        client.setFileType(FTP.BINARY_FILE_TYPE);
        client.storeFile(filename, fis);
        client.logout();
        return true;
    } catch (IOException e) {
        logger.error( "Error uploading " + filename, e );
        throw e;
    } finally {
        try {
            if (fis != null) {
                fis.close();
            }
            client.disconnect();
        } catch (IOException e) {
            logger.error("Error!", e);
        }
    }         
}
