For slab, I found that the following two patches reduce text size most (for i386 NUMAQ config) while keeping UMA path the same. I don't have actual NUMA-capable hardware so I have no way to benchmark them. Both patches move code out-of-line and thus introduce new function calls which might affect performance negatively. http://www.cs.helsinki.fi/u/penberg/linux/penberg-2.6/penberg-01-slab/slab-alloc-path-cleanup.patch http://www.cs.helsinki.fi/u/penberg/linux/penberg-2.6/penberg-01-slab/slab-reduce-text-size.patch Pekka - 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/ | ||||||||||||
