is that 4-way a 4-logical-way or 4-physical-way? If it's a 4-logical way, this workload is much closer to the best case than the worst case. I'm guessing a simple -j2 or -j3 should do much worse than that. - 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/
