Thanks Mike, 

I figured there had to be some things like that in the z9, too.

Dave,
The Z9 has lots of goodies internally that move data faster--larger
cache sizes, etc. FICON helps too.

Subject: Whoa! 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
