A noted problem was SLABs scanning of its objects every 2 seconds which caused pretty significant performance regressions due to the delay of the computation in individual threads. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
