Hi, I just do not understand why the throughputs indicated by IPERF on a GBE LAN is so very low!!! I am speaking of throughputs around 50-100 Mb/s!! I understand all the optimizations of jumbo frames(I have max'd it!) and large windows etc(which shouldnt actually matter in a LAN since the RTTs are so very low) . The two machines I am working on are not even 10 meters away!!!:)) My iSCSI application is heavily hampered by TCP. I am working with the 2.6.10 kernel..(has any one faced low throughputs in a GBE with 2.6.10? let me know ) . I would be very happy to push the TCP throughput to around 600-700 Mb/s atleast. any suggestions? Thanks Sai __________________________________ Celebrate Yahoo!'s 10th Birthday! Yahoo!
