I thought that was one of the bennefits of WM9 in conjunction w/
windows media server 9.

My problem:

I have a slow upload connection from my media server. I have some
files encoded with bandwidths higher than the upload speed. When
clients connect, the audio usually plays w/o stop, but the video is
more of a still slide show, only showing a frame or two every few
seconds.

Is there a place where I have to tell the server the maximum upload
speed that it can use? Could testing my links on the LAN throw off
the media server's knowledge of maximum available bandwidth? Any
other suggestions?

Hi Mrceolla,

To keep resource usage, including bandwidth and memory at a manageable
level you must set some server limits. You can use the IWMSServerLimits
object to specify and retrieve these settings.

You were also concerned about a slow upload connection to the media server.
If you believe that uploading content to the server is a part of your
problem you could also set publishing point limits to control and
distribute resource usage across multiple publishing points. For example,
you can put limits on one publishing point to ensure enough available
resources for a higher priority publishing points.

Please reference the links below and let us know if they help you with your
issue.

Marc,

Thank you for your reply. I will look at the links you provided in
search of a resolution. However, the slow upload connection is FROM
the server, not to the server. Let's say I have 500Mbit uploading
capabilities from my server to the client, but I have content that is
756Mbit. Since this is clearly a mismatch, I want to be able to make
sure that the client buffers enough to avoid re-buffering. Does that
make sense? Hopefully you're links will cover this issue. If not,
please respond to this and let me know how to go about fixing this
issue. Thanks.
