our project write a web server in freebsd kernel. we can receive and send data directly in kernel.Now i have some idea, i think i can creat a mbuf with cluster buffer before i send some data,because the data i want to send are all in kernel,so i can take thest data in cluster i create before,and transfer this mbuf to sosend(),then i make tcp/ip cann't release this mbuf after it received the ack.In this way, i can send data in kernel next time use the same mbuf with different cluster.i am not sure whether this way can enhance the performance.So,i hope some one can discuss with me
I don't think that what you are proposing would work. Mbuf clusters can be used in multiple mbuf chains at the same time, but I don't see how you could do that with mbufs. You probably should focus your optimization efforts elsewhere, because changing the mbuf api would make your code diverge too much from the standard FreeBSD kernel to be useful to anyone.
