measuring dm365 performances

Looking at http://processors.wiki.ti.com/index.php/DaVinci_PSP_03.01_Beta_%28r35%29_Release_Notes#Performance_-_DM365_EVM

I'm trying to abtain the same numbers with evm-dm365 (with r36 last kernel) and after with my board.

 

ETHERNET:

Using http://processors.wiki.ti.com/index.php/Iperf

I launch on the board "iperf -s"

and than on my HOST PC:

iperf -c 10.39.10.183 -w 128K
------------------------------------------------------------
Client connecting to 10.39.10.183, TCP port 5001
TCP window size:   256 KByte (WARNING: requested   128 KByte)
------------------------------------------------------------
[  3] local 10.39.10.114 port 45789 connected with 10.39.10.183 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec  84.0 MBytes  70.4 Mbits/sec

 

The iperf logs tell me it can't work at 128KB, but it uses 265KB.

I don't know if it is an important point and if it can explain the better eth performances I'm measuring (70.4 Mbits/sec > 60.3 Mbits/S) in respect of your performance table.

 

OTHER

I'd like also some ideas to reproduce all other numbers in the table.

Some of them are reproduced with iperf, but NAND, I2C, SPI, USB-MSC, ... ecc

need particular commands and setups..

 

I can re-organize the useful commands and, if not existing, I can write a wiki.

    I found the iperf known issue .. I didn't know it.

     

    Measuring performance for ETHERNET

    TARGET: iperf -s

    HOST:   iperf -c 10.39.10.183 -w 64k

    ------------------------------------------------------------
    Client connecting to 10.39.10.183, TCP port 5001
    TCP window size:   128 KByte (WARNING: requested 64.0 KByte)
    ------------------------------------------------------------
    [  3] local 10.39.10.114 port 36314 connected with 10.39.10.183 port 5001
    [ ID] Interval       Transfer     Bandwidth
    [  3]  0.0-10.0 sec  83.4 MBytes  69.9 Mbits/sec

     

    Instead Texas declares 60.3 Mbits/S

    why?

     

    Any help for measuring all other peripherals drivers?

    NAND, I2C, SPI, USB-MSC, ...

     

    Thank you,
