To be honest, I tried arch back when I was testing different SCM's for the kernel, and even just the setup confused me enough that I never got past that phase. I suspect I just tried it too early in the development cycle, and that turned me off it. Also, the oft-repeated performance issues have kept me wary about arch. Bitkeeper is quite fast, but even so Larry and friends actually ended having to make some major performance improvements to the bk-3 release simply because they were taken by surprise at just _how_ much data the kernel SCM ends up needing to process. I realize that there are a lot of advantages to keeping to high-level scripting languages for the SCM, but it's also quite important to try to avoid making the SCM itself be a distraction from a performance standpoint. However, since I never got very far with arch, I really only parrot what I've heard from others about its performance, so this may be unfair. Linus
