Just looking for 9.0 feedback (understand it's still quite new).
Although not 9.0 feedback per se.. but something to consider...
I am moving a number of machines from 8.1 to 8.4.
We use a rolling procedure with a spare:
machine A running 8.1
machine B is prepped with 8.4
change names and IPs
keep old A for a bit just in case...
The last replacement we noticed a big regression in performance. Upon
inspection the machine we replaced was 3.7.. Both 8.X and 8.X have serious
problems with a particualr query (dealing with it on performance now).
So I guess what I am trying to say... you need to test with your own data
set. That lone 8.3.7 machine was literally a fluke. We were going to move
all 8.1 to 8.4.. but at one point did one in 8.3. If we had not done that we
would not have noticed that both 8.1 and 8.4 have problems with some of our
queries.
I am even leaning now to have a lab with 8.3 for testing queries.
