[microblaze-uclinux] performance issues with NETPERF tool ..pls help

Hi All,
 
I'm using the NETPERF tool( network performance analyzer tool) to check the TCP and UDP performance between the memec P 160 M and a linux machine...
 
I'm using the following command to check it:
 
This is my devolopment board:
# ./netperf -H 172.16.1.79
TCP STREAM TEST to 172.16.1.79
Recv   Send    Send
Socket Socket  Message  Elapsed
Size   Size    Size     Time     Throughput
bytes  bytes   bytes    secs.    10^6bits/sec

 87380  16384  16384    0.97       -2.00

 

=============

and my netserver is running on the Linux machine like this:

#./netserver

I'm not able to understand the Throughput of my board ...... Y is it showing so less and why is it negative???

 

Whereas , i tried the netperf tool with 2 linux machines and i got the following output:

# ./netperf -H 172.16.1.79

TCP REQUEST/RESPONSE TEST to 172.16.1.79
Recv      Send           Send          Resp.        Elapsed  Trans.

Socket   Socket       Message
Send      Size           Size          Time           Rate
bytes     bytes          bytes        secs.          per sec

87380    16384         16384        10.00           93.79

===================================================

 
 
 
 
BUT , when i give the following command for the board to linux machine : i get the following..
 

# ./netperf -H 172.16.1.79 -t TCP_RR
TCP REQUEST/RESPONSE TEST to 172.16.1.79
Local /Remote
Socket Size   Request  Resp.   Elapsed  Trans.
Send   Recv   Size     Size    Time     Rate
bytes  Bytes  bytes    bytes   secs.    per sec

16384  43689  1        1       10.00      48.11
16384  87380

And , when i give the following command for 2 linux machine : i get the following..
 
# ./netperf -H 172.16.1.79 -t TCP_RR
TCP REQUEST/RESPONSE TEST to 172.16.1.79
Local /Remote
Socket Size   Request  Resp.   Elapsed      Trans.
Send   Recv   Size        Size    Time           Rate
bytes  Bytes  bytes      bytes   secs.         per sec

16384  87380  1            1       10.00           7043.25
16384  87380

 
Can some 1 help me.. as to y is there so much of difference ??? and can some 1 tell me the exact way to read this output...
