This is after memory is taken away for the kernel itself and the kernel heap. The amount that is reserved for kernel vs. user space is configurable in the pc kernel witht he "*kernelpercent" argument (see plan9.ini(8)). If unspecified it will default to between 40% and 70% of memory going to userspace. This seems like a lot of reserved kernel memory to me on large memory systems (such as yours), but I dont know all of the implications of using a very low kernel percent. Btw, any setting lower than 10% will revert to the default. > ++pac. Tim N.
