Since I will soon be using a DG 4000, I would like DG specialists to give me reasons why DG 5010 server has so BAD results compared with MIPS 3240 for example, and with other m88k based machines, like Motorola Delta 8864SP. One reason someone gave us here was the VERY SMALL cache (2x16Ko). I must admit I can't understand why not more. Any more reasons ?

Benchmark numbers are relative to VAX 11/780 = 1.0, so higher numbers are better. The programs gcc, espresso, spice, doduc, nasa7, ll, eqntolt, matrix300, fpppp and tomcatv are real programs, not synthetic or toy codes. The SPECmark is the geometric mean of the ten benchmark programs (the Nth root of the product of the membmers of a list with 10 members). An examination of the numbers would lead one to conclude that the benchmarks are heavily affected by the system as a whole, not just the processor. Such things as cache size/speed, memory speed and disk access speed must contribute significantly to the results. Also, the 88k systems typically have 1/4 as much cache as some of the competing Rx000 and SPARC systems (32k versus 128k), even though the 88k is quite capable of supporting 128k of cache. If someone could supply more information about each benchmark, and each system (cache size, CPU clock rate, etc), that might prove enlightening. ____"Congress shall have the power to prohibit speech offensive to Congress"____ Alan Lovejoy; alan@pdn; 813-530-2211; AT&T Paradyne: 8550 Ulmerton, Largo, FL.
