This seems to be a popular misconception. Yes, page-coloring obviously plays no role as long as your cache no bigger than PAGE_SIZE*ASSOCIATIVITY. IIRC, Xeon can have up to 1MB of cache and I bet that it doesn't have a 1MB/4KB=256-way associative cache. Thus, I'm quite confident that it's possible to observe significant page-coloring effects even on a Xeon. --david - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
