用java在同一台机器上从客户端复制文件到服务器？

我正在将一个300 MB的大文件从客户端复制到服务器。我在本地设置了客户端和服务器weblogic，但传输速度太慢。只有当我的服务器与客户机在同一台机器上时，才有办法提高速度吗？以下是我正在使用的代码：

boolean decodeStream = false;
bytesRead = istream.read(buffer, 0, BUFFER_SIZE);
if (bytesRead != -1 && Base64.isArrayByteBase64(buffer))
{
  decodeStream = true;
}
istream.close();

//write the file to the file specified
// if createFile then create a new file
// otherwise append.
OutputStream bos = new FileOutputStream(fileNamePath, !createFile); // second parameter, if true then append...
istream         = file.getInputStream();

if (decodeStream)
{
  // File is encoded, decode it.
  Logger.log("(perform) Decoding file: " + fileNamePath, _moduleName, Logger.DEBUG);

  // Stream came in encoded, so we need to decode it.
  Base64.InputStream stream = new Base64.InputStream(istream);

  while ((bytesRead = stream.read(buffer, 0, BUFFER_SIZE)) != -1)
  {
    bos.write(buffer, 0, bytesRead);
  }

  stream.close();
}
else
{
  // File is not encoded.
  while ((bytesRead = istream.read(buffer, 0, BUFFER_SIZE)) != -1)
  {
    bos.write(buffer, 0, bytesRead);
  }
}

您可以通过使用缓冲io来提高速度

OutputStream bos = new BufferedOutputStream(FileOutputStream(fileNamePath, !createFile));
istream         = new BufferedInputStream(file.getInputStream());

默认情况下，JVM使用8kB的缓冲区。我不知道您的缓冲区大小。
