I am just curious if anyone can suggest some possible brands and or system architectures that would optimize I/O operations. I have written some code that will transmit large amounts of multicast socket traffic and I would like to run it on a system optimized for that sole task. I have heard that opterons perform well but I would like to hear some suggestions and why you think it would help. I would also prefer to run Redhat Linux on the system if that helps in the decision. Thank You
