I tuned and tuned. I'm pretty good at tuning VMS, but I never could get it back to pre-5.0 speeds. Of course it sped up a lot in later releases as you said. The last I ran in production was 5.4. Our hardware was a VAX-11/750, a MicroVAX-II, two MicroVAX-3600s. The first two machines were cleared for classified processing, so upgrading them to newer hardware would've been a years-long process. They're probably still there. -Dave On 12/23/2012 05:58 PM, Steve Davidson wrote: Tuning IS everything... That said, V5.0 was (is) slow, but 5.5 is not. I ran it on VAX-11/780, VAX-11/782, VAX-11/785 and 8000 class machines. The ONLY complaint I ever had was disk space (or lack thereof). Remember that this was a development environment in DEC at ZKO (Spitbrook Rd, Nashua, NH) and those users wanted the fastest at all times - no excuses! Again, tuning IS everything... -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Dave McGuire Sent: Sunday, December 23, 2012 17:50 To: hecnet at Update.UU.SE Subject: Re: [HECnet] Older VAXVMS Install kits?

It has so many more capabilities and toys/tools! But oohhhhh soooo painfully slow compared to v4.7. You wouldn't believe the complaints I endured from my users on Monday after spending all weekend doing an upgrade to 5.0. They loved me before that! -Dave -- Dave McGuire, AK4HZ New Kensington, PA -- Dave McGuire, AK4HZ New Kensington, PA
