The slow, old, and heavy boxes go first, of course. I remember taking a trip with Stan Sieler in the Bay Area where he took me to a scrap facility. There, shrink wrapped on the outside of a pallette, were HP 2645 terminals, right alongside Compaq boxes.
Relative performance charts can be our friend as we triage our older HP gear. There's an adequate one available online at bitsavers.org as part of a breezy page covering the history of the 3000.
We've got The One Chart to Rule Them All you can download to use while you have HP's gear on the chopping block. There's a section for A-Class comparisons, and another compares HP's boxes in the N-Class line to older system performance.
Such numbers are relative in more ways than just the comparison between servers. HP actually massaged the numbers themselves back in the late 1990s. Our story in 1998 reported that
HP is “restating” the performance rankings for much of its hardware, starting with this month’s rollout of the Series 989 systems. The new rating is an HP 3000 Performance Unit, not based on Series 918 performance. And the new numbers are between 29 and 52 percent higher for all systems except HP’s largest ones, the Series 996 and 997 units.
As I observed, while looking askance at the new figures, "HP wants you to think of HP 3000s as faster than ever, but its new rating measurements don’t really make existing systems any faster. They just sport higher numbers than they did last month."
There was some technical logic to the HP adjustment. The 3000 hardware from HP had just acquired some newer and faster cousins.
Dave Snow, product manager for the 3000, said "the measuring techniques for our midrange and high-end platforms were producing results that were not consistent with each other. You had a 918 performance for the midrange and a different relative performance for the high end, but the two relative performance numbers weren’t the same.”
The discrepancy was a big deal, he added, “but it was a big deal we could sort of live with, so long as the 9x9 and 99x performances were dramatically different from each other,” Snow said. “As we added performance to the 9x9 platform, it is approaching the 99x. That’s caused us to have this quandary. In some sense we’ve had two different sets of 918 numbers. We had to bite the bullet and reconcile the numbers."
