My slab tools for benchmarking the fastpath is here: https://github.com/netoptimizer/prototype-kernel/blob/master/kernel/mm/slab_bulk_test01.c And I also carry a version of Christoph's slab bench tool: https://github.com/netoptimizer/prototype-kernel/blob/master/kernel/mm/slab_test.c -- 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
