Query related to ethernet

We have 10/100/1000 Mbps Ethernet port on DM6467 DVEVM board, I would like to know what is the maximum amount of data that we can transfer over Ethernet (Considering all other hardware, protocol overheads etc) and what are the parameters on which it is dependent.

    This is a very good question and hopefully I can do this topic justice. 

    The short answer is, for a hardware perspective, see this document.  From a software perspective, we have seen performance number max out at ~ 180 MBits/sec (see LSP release notes).  Though this number may seem low for a Gbit ethernet device, keep in mind that in the embedded space this is primarily constrained by CPU (ARM in this case), you will find it difficult or impossible to find a part which approximate the performance the hardware can support.  In the embedded space, Gbit ethernet is primarily available for connectivity compatibility.  If you are interested in learning more about what factors affect ethernet performace (including CPU bandwidth), see this wiki topic

    Is the ethernet performance numbers are same for both 594MHz and 729MHz boards ? if not what are the numbers ?
