FreeBSD is not a linux flavor.. Besides if you dont tune th HZ option in freebsd you will have a terrible loadaverage.. I set up a hlds/cs server with freebsd on a p3 500 and have it only to use aprox 50% CPU. (with all that fancy VAC support) without vac it goes down to aprox 25-30%. Since hlds is not freebsd native, it has to be emulated. thus means that hlds can only utilize 50 tics instead of 100 which is the kernel default. a value of 1000 seems to be a good value. >From FreeBSD LINT (kernel reference configuration) # The granularity of operation is controlled by the kernel option HZ whose # default value (100) means a granularity of 10ms (1s/HZ). that means that a hlds package can only be calculated every 20 ms. raising the value to 1000 it can calculate every 2 ms. There is some other tweaks that you can probably do.. but raising the HZ value do wonders... My server is running pingbooster3 on a p3 500.. and the CPU usage are then up to 80%... /Bjorn Have you noticed that if you take Windows ME, NT, and CE, and arrange them in a certain order you get Windows CEMENT.......coincidence, i think not!!!! _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux
