Perhaps that would be enough to find this performance > discrepancy between slab and slub? You could simulate that by just sending packets using unix sockets between threads bound to different CPUs. Sending a packet allocates; receiving deallocates. But it's not clear that will really simulate the cache bounce environment of the database test. I don't think all passing of data between CPUs using slub objects is slow. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
