Hello Peter,
in your kernel, try : options VM_KMEM_SIZE_SCALE options DEVICE_POLLING options HZ=1000 You say that you do not have any firewall, so why do you use: net.inet.ip.fw.dyn_udp_lifetime=10 net.inet.ip.fw.dyn_buckets=1024 you may add: kern.polling.enable=1 kern.polling.user_frac=50 best regards, Mathieu CHATEAU Thursday, May 26, 2005, 7:47:48 PM, you wrote: PK> Hello guys, PK> I'm not quite sure if this is the right list to address this to, as it's partly PK> a performance problem and partly otherwise.
