I want most of this RAM to be used for the buffer cache. I have been playing with cpu_startup() (i386/i386/machdep.c) with the intention of increasing 'nbuf' but I am limited by the size of the 'kernel_map'. kernel_map is limited to 1GB (am I right?). Is there a way to use >1GB of kernel virtual address space? thanks, Rohit. _____________________________________________________________ http://www.gojuryu.com .
