Thanks Mike, I figured there had to be some things like that in the z9, too. Dave Dave Stuart Prin. Info.

That Thing's Fast! Afternoon all, We installed a z9 F01 and a DS6800 into Production over the weekend, and I'm just wondering if what I am seeing is normal, or if I should start looking for the shoe that's about to drop. We went from a 9672-RA6 (@89 mips*) with a 9393-T82 RAMAC II with 8 ESCON channels to a 2096-F01 (@87 mips*) with a DS6800 with 4 FICON channels (hey, they sent me 4 cables!). Based on posts to the list, I knew the DS6800 was faster that the 9393, and I was expecting to see some reductions in our batch processing times. Something on the order of 60 - 90 minutes. And the OSA/Express is 100mbps vs the OSA/2 at 10mbps. The nightly batch for our financial management system, our longest running batch stream, was running between 9 - 10 hours a night last week. The two night average so far for Monday and Tuesday nights, is about 5:45. And the FTP to load the data warehouse is running in 1 hour, vs 2 hours last week. Granted, we've only run normal production for two nights, but is my experience average? Above average? Way above average? Do I need to look for that dropping shoe? And yes, I understand YMMV very well, thank you. Dave * Depending on which performance/capacity chart you look at. Dave Stuart Prin. Info.
