Very interesting. Of course, toy benchmarks are not an indication of real
system performance (what happens when you fill the cache, how fast is
paging, etc. ...?). I'm using a DECstation 3100 for my programming at the
moment. Has anyone had the opportunity to benchmark compiles of C++ on the
two? If not, can anyone lend me a NeXT so I can do it?
