We’re in the process of building a domain index, and I’m seeing performance numbers all over the map. One day it indexes 40GB of data / 6 GB of ft indices / 450k documents. Another day it is 21GB of data / 4GB of ft indices / 180k documents. These numbers are just all over the map.
Any ideas on how to improve and maximize DI performance? The system is a quad CPU box with 4 GB of RAM. Plenty of power and RAM. DI Threads is set to eight.

Hi David,
indexing is very I/O intensive
so the disks should be the first point to look for.
what type of Disks is your DI server working on
local Raid1 or 5 or SAN?
and the second part is
what are the servers doing where the DI reads the data from.
backup
indexing
replication
…
you see a lot of points to look for
have fun
regards
Herbert

Can I ask a stupid question? (No that was not the stupid question). How did you get these DI stats?

Yes, you may ask a stupid question.
Well, actually, there are no stupid questions. There are stupid answers, and the occasional flip answer, but no stupid questions.
On to a serious answer.
The information comes from the Domain Catalog. I merged together information from the Domain Index Status views with information from the Databases view.
