SMP support in 4.x will use as many as you have, but FreeBSD 4.x does not make optimal use of extra CPUs and you hit diminishing returns with more than about 4 CPUs (the SMP support in 4.x has limitations: only one CPU can execute in the kernel at once). SMP support is being dramatically improved in 5.0-CURRENT and will end up being highly scalable (it's not quite there yet). > When will FreeBSD be able to run on ia64? Now (5.0-CURRENT runs on ia64). > How many ram (DDR-ram? or what should I use?) You can't use more than 4GB on ia32. > How many hard-disks (not using RAID and with RAID)?
