    	   out.write("Server is listening on port " + i+ " of " + remote );
    	   out.newLine();
    	   s.close();

       } catch (IOException ex) {
    	   out.write("Server is not listening on port " + i+ " of " + remote);
    	   out.newLine();
    }
       i++;
       } while(i <= 55000);
       out.close();
       
}}

Define 'slow'...you are connecting to a Socket 55,000 times repetitively, and most likely thousand of exceptions are thrown in the process, how fast do you think its going to run?
