I will say, however, that the virtual memory system on the NeXT is quite sophisticated and I believe it utilizes memory and it pages quite efficiently. So, 16mb has been quite adequate in my use. Below are results of running the Stanford Lisp Timing Project benchmarks on an 040 NeXTstation machine with 16mb of memory and local disk. They were not run in single-user mode, but there wasn't much going on at the time.
