Heavy parallel make throughput is still down a little over 10%, but X choppiness is markedly improved. Test-starve is now working. One thing that I noticed is that irman takes quite a bit longer to complete than with stock. I've attached the results of that, plus some contest numbers. My local variant of contest has a couple of differences to stock: dbench doesn't run so many instances, and list_load is just a small tree being md5summed. There are two additional loads as well. ab_load is an ancient apache bench jabbering with an also ancient apache (boring static page via localhost)... you can guess what irman2_load is :)
