Streaming video performance problems
« on: March 26, 2002, 08:46:07 AM »
Any client PC attached to the SME 5.1 gateway suffers extremely poor performance with streaming media.  This includes both Windows Media Player
as well as RealPlayer.  The server is connected to a DSL line that consistently
gets 1.2 megabits/sec at the client when performing various speed tests.
 
If I boot Win2K on the server instead of SME, the server can stream the media into Windows Media Player with no apparent performance problems.  
 
I suspect that something is not tweaked properly in SME in order to handle the streaming media.

Does anyone have a suggestion?
 
Thanks,
Mike

I've seen similar problems downloading.

If I download directly to the server from source a, i get 80k/s, however if i download the same file through a 100Mbit switch to a client, i can only manage up to 20k/s at best from source a.

I would have expected better xfer rates for one extra hop to a client when that is the only b/w on the nextwork.

I would look at the switch and other hardware in this case. I have streamed 3 simultaneous .vob files (DVDs in other words) from a SCSI backend through an e-smith (only a 4.1.2 at that) across a LAN with nary a jerk on any screen. Good hardware involved.

Just a thought.

I routinely look at video w/ver 5 and have no problems
