Copy large size file takes longer time

Hi All,
I would like to have advice on multiple issues, code snippet java code.

void test(){
SmbFile sFile = null;
NtlmPasswordAuthentication auth = new
NtlmPasswordAuthentication(activeUserDomain, activeUserID, activePwd);
sFile = new SmbFile("smb:"+absoluteFilePath.replaceAll("\\\\", "/"), auth);

File inFile = new File(tempZipDir,zipFileName);
inFile.createNewFile();
DataOutputStream outZ = new DataOutputStream(new FileOutputStream(inFile));
InputStream inZ = sFile.getInputStream();
copyStreams(inZ,outZ);
}

private static final void copyStreams ( InputStream in, OutputStream out )
throws IOException
    {
     byte [  ]  buffer = new byte[1024];
     int len;


     while (  ( len = in.read(buffer)) >= 0 )  {
       out.write( buffer, 0, len ) ;
     }

     in.close() ;
     out.close() ;
    }

1. Above snippet of code setup locally, worked for sometime, once I got
connection time error, since than always  throws  below exception, similar
behavior in my secondary machine as well, please advice, what might causing?

java.net.ConnectException: Connection timed out: connect

 at java.lang.Thread.run(Thread.java:745

2. I am very new to smb implementation, I am trying to trouble shoot
performance issue on existing implementation, same code have been working
for years i.e. to copy zip file(3KB to 800MB) from samba server to
appserver but since recent time copy function takes long time for a give
file, please advice what might cause?
