Dear All,

               I would like to know whether there is any difference in network architecture between Tiger 10.4.11 and Leopard?. Previously I developed a Network Kernel Extension [ Particularly a Virtual Network Driver for Link aggregation] module for Tiger.It was working extremely good in Tiger.Now I changed My Operating System to Leopard.In Leopard OS also the same Network Kernel Extension that was used in Tiger OS was installed and run.But the performance is very very Low.In Tiger we got the bandwidth 230MB/Sec but the Leopard we got only 20MB/Sec.We also used this Network Kernel Extension in Leopard after compiled with the Leopard OS.But the Performance is same [Only 20MB/Sec].Can you lease tell me is there any change in the MBUF structure in Leopard?. Where I focus to resolve this problem?.
 
Thanks & Regards
Anees
