Dear Mohammad,
ML403---PC : 410Mbits/s
PC---ML403 : 210Mbits/s
These results are interesting
for TCP. Jumbo-frame of 8982 will
almost double this number.
Have fun.

Use the following command in Linux please:
ifconfig eth0 mtu 8982
As well you should do that on your PC

Dear Mohammad,
The results are as follows:
PC--ML403
TCP_SENDFILE : 38Mbps
ML403---PC
TCP_SENDFILE: 155Mbps
This result is unreasonable. Because PC is more

Use the following command in Linux please:
ifconfig eth0 mtu 8982
As well you should do that on your PC in the measurement.

Hi,
We need to findout where is the bottlenect.
1. Run vmstat on the ML403 board and find out the percentage CPU is busy
when you are transferring the file. That will show if cpu is busy or not.
2. Run oprofile and find out which are the routines eating away the cpu
time.
Once we have data
I was able to achieve ~320 Mbit/sec data rate using the Gigabit System
Reference Design (GSRD XAPP535/536) from Xilinx. This utilizes the
LocalLink TEMAC to perform the transfers. The reference design provides the
Linux 2.4 drivers that can be ported to Linux 2.6 with a little effort.
This
thing near 60Mbps.

Use
Dear Mohammad,
There are some parameters which could be adjusted to improve the
performance. They are: TX and RX_Threshold TX and RX_waitbound. In my
system, we use TX_Threshold=16 and Rx_Threshold=8 and both waitbound=1.
Also Jumbo frame of 8982 could be enable.
Try those hints and share your
thinking that it is enabled by default. Is it?
thanks
