Default microblaze uclinux ping delay

Hi all,
I'm evaluating the porting of uclinux on microblaze.
now I'm performing a ping between a laptop PC and microblaze and what I
can see is that the
averange delay is about 6.8ms... that is a lot of time !.... with a
point to point connection I'm expecting less then 1 msec.!

64 bytes from 10.0.0.1: icmp_seq=475 ttl=128 time=6.9 ms
64 bytes from 10.0.0.1: icmp_seq=476 ttl=128 time=6.8 ms
64 bytes from 10.0.0.1: icmp_seq=477 ttl=128 time=6.6 ms
64 bytes from 10.0.0.1: icmp_seq=478 ttl=128 time=6.3 ms
64 bytes from 10.0.0.1: icmp_seq=479 ttl=128 time=6.9 ms

Does anybody has better performance?

Thanks in advance,
Francesco

Sorry I not tried but I would like to buy the same board (I sow in
other post you are using an ml403) and play with the ethernet...

If your laptop is linux... you can try
ping -f 10.0.0.1
and after a while if you interrupt (Ctrl-c) you can see some other
statistics.
If your screen fill with dots during the ping then there are very poor
performances and/or some cable problem and/or some negotiation
problem....
