Turning on NO_HZ on RSDL greatly improved it. I have not tried NO_HZ on mainline. The first test was with NO_HZ=n, the second was with NO_HZ=y. My baseline test was with mainline NO_HZ=y. As an aside, we should not name config options NO_* or DISABLE_* because of the potential for double negation. -- Mathematics is the supreme nostalgia of our time. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
