iTunes Video and 100% CPU

ScottG
When I download videos to itunes on my Mac, my astaro CPU utilization jumps to 100% and the whole network bogs down as a result.  I use Astaro 7.002 in my home connected to a cable modem.  Astaro is running on an old desktop PC: 
Pentium III (Coppermine), 600 MHz
377MB RAM 
12GB Hard Drive
NIC: Accton EN-1207D Fast Ethernet Adapter
NIC: Accton EN-1207D Fast Ethernet Adapter
NIC: IBM 10/100 Ethernet Server Adapter

This isn't a a very powerful PC, but I thought for a firewall running on Linux, this would be more then enough for a small home network.  Is there some setting I can adjust to reduce the CPU load?  Could it be a bug with Astaro and this type of traffic.  

I have the dual virus protect on.  For HTTP I have basic user authentication enabled.

    Try logging on via SSH and run top while you are using ITunes.  You should be able to see what process is hogging the CPU that way.

    I'm not a Linux guy.  I can login via SSH, but I don't know what it means to run top.

    If you can get in via SSH:
    after logging in, elevate your priveleges via SU:

    type in "SU" and press Enter
    Enter the root password you setup during installation (if you forgot this, just go into WebAdmin and reset it)

    now your prompt should look like this:

    astarohostname#

    type in "top" and press Enter.

    Top runs, and it works much like Task Manager does in Windows... the top processes will be, well, at the top of the list.  Try ITunes and see what process(es) go crazy.  When you're done, just type the letter "q" into top and it will exit.  Enter Exit two more times and you're out!

    FWIW, you don't need to su before running top.

    Barry's right, I'm just real used to being on as root, as I often am tinkering with other things on our test system(s).  You can run top as the "loginuser".

    The two top processes are httpproxy (around 40-70% CPU) and mysqld (around 20% CPU).

    How much bandwidth do you have, and how fast does the video download?

    I have a cable modem that's pretty fast.  I want to pcpitstop.com/internet/bandwidth.asp and did a download test.  The result was 2557 kilobits per second.

    I downloaded two videos in iTunes, one 37mb the other 12 mb.  Both downloaded at about 0.133 MB/Sec

    Hmm... sounds like a possible bug in the http proxy.

    What about other large downloads via http?
