That kernel's config file has: # CONFIG_SMP is not set That means no multiprocessor support (i.e. a single CPU core will be used all the time regardless of their actual number). > Oh, and what is `NX/XD'? https://en.wikipedia.org/wiki/NX_bit It's considered a good thing to have one in CPU generally, as implementing said bit in-kernel will hurt performance.
