[squid-users] streaming and performance problems

Hi,

In my setup, I am streaming live television from a streaming service
in the Netherlands through Squid deployed on a Ubuntu server in the
Netherlands to a Windows machine in Japan. I am the one and only user
of the Squid server. I view .wmv stream in Explorer using Windows
Media Player. The connection speed is excellent (I tested this with
downloading files from various servers in Explorer). Still, after
about one minute of perfect play, the image keeps rebuffering and the
image freezes. I tried many things, but I just cannot get it to work
properly.

In the Squid log-file, it I get the following entries from the start
until before the end of the stream:

1252558617.468     80 202.223.121.120 TCP_MISS/200 375 GET

Is there anything I can do to fix this? What can I try more to get
this to work properly?

Below this email my Squid configuration. To improve performance, I
tried to switch off caching and increase the read_ahead_gap. I hope I
did it correctly. Though, it did not help unfortunately.

Thank you!
Andrej
