That's all I'm saying. What does your SA>kernel config look like? Do you have all of the debug stuff turned SA>on? I have actually two machines and two kernels: one machine runs with WITNESS and DIAGNOSTICS and the other without that. On both machines the current kernel is three times slower than the old kernel. Of course the debugging kernels are even slower than the non-debugging ones. But, the three times ratio between old and new kernels is the same on both machines. harti -- harti brandt, http://www.fokus.fraunhofer.de/research/cc/cats/employees/hartmut.brandt/private brandt@fokus.fraunhofer.de, harti@freebsd.org
