I think you missed the point. I didn't do parameter tuning for my benchmarks. I hate tuning parameters, they are huge problem for users of the kernel. My point is that I want to implement auto-tuning in the SLUB allocator. This network stack use-case, will just be one use-case where the auto-tuning need to show improvements. It is not that complicated. FreeBSD have this kind of auto-tuning to the workload in their slab implementation. -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat Author of http://www.iptv-analyzer.org LinkedIn: http://www.linkedin.com/in/brouer
