peers-js delay on web actions

[pabloandres]

Hi yohannmartineau,

first of all great work!

I downloaded the svn trunk version of the project a couple of days ago.
I'm currently working with the peers-js and having an small but annoying problem.

When i click on the "call" button it takes 5 secs to actually make the call.
Doing some debug and research on the code, I found that on method UdpMessageSender.sendBytes

       try {
            System.out.println(dateFormat.format(new Date())   " UdpMessageSender.sendBytes b");
            datagramSocket.send(packet);
            System.out.println(dateFormat.format(new Date())   " UdpMessageSender.sendBytes a");
        } catch (Throwable t) {
            logger.error("throwable", new Exception(t));
        }

the datagramSocket.send(packet); takes almost 5 seconds.

2012-06-15- 19:13:44:770 ::: UdpMessageSender.sendBytes
2012-06-15- 19:13:44:770 ::: UdpMessageSender.sendBytes packet created
2012-06-15- 19:13:44:770 ::: UdpMessageSender.sendBytes b
2012-06-15- 19:13:49:818 ::: UdpMessageSender.sendBytes a

I also implemented the "terminate button" on the web and the same happens.
But the weird thing is that it only happens when i issue any action from the web side. But when for example the ringing message is sent by the applications, it's sended instantly.

Do you have any clue on what could be happening?

Thanks in advance.

Let me add.. both client and server are on the same lan.
And client java:

java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2)
OpenJDK Server VM (build 20.0-b11, mixed mode)

OS: Ubuntu 11.10

Let me know if you need some additional info.
Best regards

I added those catch throwable because i had an issue while sending packets (a security issue iirc). Unfortunately, I don't know why you're getting those delays. My security exception was also coming from web integration. With jnlp and standalone versions, no problem. I wonder if it's browser related. Did you make a test on IE on a windows pc? I think there's a sort of security scanner embedded in firefox or chrome and maybe this security scanner is slowing down the first packets sent…

Hi yohannmartineau, thanks for replying.

I tested on a windows pc and there is no delay. So maybe it's OS related and I think there's nothing I can do to avoid it. Anyway I'll let you know if I find something else.

Thanks again.
Best Regards

Hi,

It wasn't OS related. It was about the JDK.
I removed OpenJDK and installed oracle-jdk7-installer and it started working ok.
My Java version now

java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b05)
Java HotSpot(TM) Server VM (build 23.1-b03, mixed mode)

For those people that work with Ubuntu and OpenJDK, these are the steps I follow to move to oracle-jdk

1. Add repository to /etc/apt/sources.liist

deb http://ppa.launchpad.net/webupd8team/java/ubuntu  main

2. Install oracle-jdk7-installer

sudo apt-get update
sudo apt-get install oracle-jdk7-installer

And ready to go..

pablo@devel220:~$ java -version
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b05)
Java HotSpot(TM) Server VM (build 23.1-b03, mixed mode)

It updates also the borwser plugin.

Hope it helps.
Best Regards.
