Java socket delay

I am going to read from a socket in java. Here is what I am going to do:

Sy开发者_JAVA百科stem.out.println("Start Reading");
/* bab is socket connector */
/* and readLine is the method below.
/* public String readLine()throws IOException
{
    String a = inStream.readLine();
    return a;
}
*/
for( int j=0;j<9;j++)
{
    response = bab.readLine();
    System.out.println(response);
}

I see a lot of delay (2-3 seconds) between printing "start Reading" and first line of the response. But when I requested it with Firefox, it responsed quickly (20 ms). What is the problem? And how can I solve this problem?

I suspect the reason is the server doesn't send the line-delimiter for some time, so the readLine() method waits. I bet if you just do readByte() it must be quick.

As Firefox or any other browser wouldn't read line by line, it dosn't affect them.

Firefox is probably caching the response and is therefore able to display it very quickly to you. I suggest you clear the cache on Firefox and time it again.

If you are using a domain name for the call then Firefox will also cache the DNS lookup which could save time in Firefox whereas making the call in Java could require a DNS lookup.

If you are using Windows then download Fiddler which will allow you to monitor the HTTP connection and give you a better idea of what is happening.
