AM3892 Gigabit performance

Any reply?

Hello,

I don't think that just a CPU boost will do the trick. You can try to use jumbo frames; increase the MTU size as much as possible and test again. Please, tell me what was the maximum value you was allowed to set.

Hi Viladimir,

I have not an EVM. I see from PSP_04.00.00.13 performance guide with iperf.

Thanks for your reply.

Hello,

You don't have such hardware at all. You just want someone to provide you with real iperf results on EVM that can reach 900Mbit or 1Gbit, letting you to know that that is possible. Is that correct?

Hello Viladimir,

Yes,that is correct.

Hello,

Is this the performance guide you are looking at:

http://processors.wiki.ti.com/index.php/DM816x_AM389x_PSP_04.00.01.13_Feature_Performance_Guide#Ethernet_Driver

In some cases here we have bandwidth near 800 Mbits/sec. I think this performance could depend on many things. As far as I can see there are no newer performance guides (for this platform), nor performance guides for above 1GHz CPUs here. You can speak again with your local field engineer, but I am not sure that it is possible to request these performance lists.

Hello,

Here is the new 04.04 Feature Performance Guide:
