ping only tests latency *not* throughput. So it is not really a good test.

	what kind of bandwidth you max out using that.  Or use ping with -i & -s 
	set to reasonable values depending on whether you're using jumbo frames or

	If the problem is your connection is dropping a few packets, this will show
