to be allocated at boot time. This is an expensive option, as they consume physical ram and are not pageable etc. In certain situations, this kind of option is quite useful, especially for news servers that access a large number of directories at random and torture the name cache. Defining 5000 or 10000 extra vnodes should cut down the amount of vnode recycling somewhat, which should allow better name and directory caching etc. This is a "your mileage may vary" option, with no real indication of what works best for your machine except trial and error. Too many will cost you ram that you could otherwise use for disk buffers etc. This is based on something John Dyson mentioned to me a while ago.
