Faster, multi-CPU hardware will not help. The tinderbox is constrained by memory bandwidth, not CPU speed. A cluster of seven $200 Mini-ITX boxes can do a full -CURRENT tinderbox run in two or three hours, vs. eight to ten hours on a single $1400 box. Ccache won't help either, because buildworld always starts by building a new toolchain, which invalidates the cache. DES --=20 Dag-Erling Sm=F8rgrav - des@des.no
