While I'd certainly concur heartily in general, be careful to note that the 2-4 ratio is OK for integer work. For floating-point, the ratios are all over the map, and sometimes the uVAXen (esp. under VMS) even outperform the Suns, esp. when using 68881s. Most micros are much better at integer work than at floating-point, at least relative to the VAXen [or maybe that says that the VAXen have either over-powered FP, or under-powered integer!] -- -john mashey DISCLAIMER: UUCP: {decvax,ucbvax,ihnp4}!decwrl!mips!mash, DDD: 408-720-1700, x253 USPS: MIPS Computer Systems, 930 E.
