On a dual-core I can't notice any difference between the fully loaded huge-smp and the modular one when booting. Same goes for an old single-processor AMD Duron actually. I'm not sure that recompiling is worth it if the only objective is speed increase either. How much is a split second worth to you?

How much is a split second worth to you? I can definitely vouch for this. Compiling your kernel for speed or optimization generally causes more trouble than it is worth. On the other hand, if there is a module that is not compiled and you need it, you can usually selectively compile only that module and integrate it in with an existing generic kernel. If you want to do something else, more specialized, then the usual mantra is, "If you need it, you won't be asking about it." Aaron W. Hsu -- A professor is one who talks in someone else's sleep. |
