Hi Steve,

Thanks for the interest in the IP Camera.

I think we're looking at a very slow VGA frame rate of about between 0.2 and 0.5 frames per second over Ethernet currently.

The problem is the 'delayed ACK throughput degradation' situation with the uIP protocol stack. It transmits one segment at a time, and clients such as Winsock delay for a short time before acknowledging single segments. That slows things down considerably.

There is a fix for uIP that makes it emit 2 segments at a time, thereby eliciting an immediate ACK from the client. I spent 2 days trying to get that going, but then had to focus elsewhere.

The project is far from complete, and when I get some more time I'll have another crack at the throughput booster hack code. The frame rate is expected to climb by an order of magnitude as a result.

Regards,
Murray R. Van Luyn.
