[realtek] Odd behaviour (ping take 3 seconds while normally it takes 1 ms)

Wed Mar 27 04:20:01 2002

When I do a ping command I get the following output:

I am not a network expert but the ouput looks stange

The order changes and some packages are lost, other have long delay. 

This 'error' especially occurs during and after heavy network traffic. 
Other network commands also become slow.

I noticed this behaviour disappears after reconfiguring the card.

Can you help me making sense of this. 

The question is how to solve this. Reconfiguring the (ifconfig) the
network is not a serious option. (May be I should change the card or
the driver).
