>Question/Comment:
>Using the same network test bed with 100-Mbps Ethernet links and 8-Mbps
ATM PVC's, I ran multicast test cases using:
>(1) IPERF 1.7 on a pair of Linux Dell rack-mounted PC's, and
>(2) IPERF 1.7 on a pair of Windows XP IBM laptops.
>
>Via Linux IPERF, I can generate a multicast stream up to 6.3 Mbps without
errors or data loss.
>Via Windows IPERF, I can generate a multicast stream up to 5.5 Mbps
without errors or data loss.
>
>While there are differences in the source and receiving PC's, the data
rates are low enough that the hardware differences should not be important.
What else may account for such a performance difference between the Linux
and Windows version of IPERF? Is this a known problem?
